1001. Introduction

The Marine Corps, within the Department of the

Navy, is organized as a general purpose “force in

readiness” to support national needs. Deploying for

combat as combined-arms Marine air-ground task

forces (MAGTFs), the Marine Corps provides the

National Command Authorities (NCA) with a

responsive force that can conduct operations across

the spectrum of conflict. Recent events continue to

highlight the Navy-Marine Corps team’s key national

security role. Seabased, combat ready, forward

deployed naval forces have been involved in more

than 28 major military operations since 1995.

Whether responding to natural disasters or to the

specter of regional aggression, Navy and Marine

forces provide self-contained and self-sustained air,

land, and sea strike forces, operating from a

protected sea base, that can be tailored to meet any

contingency.

1002. Organization and Chain of Command

Two parallel chains of command—Service and

operational—exist within the Marine Corps. The

Service chain begins with the President, through the

Secretary of Defense, and continues through the

Secretary of the Navy and the Commandant of the

Marine Corps. The operational chain runs from the

President, through the Secretary of Defense, directly

to commanders of combatant commands for missions

and forces assigned to their commands. Marine

Corps component commanders provide operational

forces to commanders of combatant commands and

other operational commanders as required. 

The Marine Corps is divided into four broad

categories: operating forces; the Marine Corps

Reserve; the supporting establishment; and

Headquarters, U.S. Marine Corps.

1003. Marine Corps Operating Forces

The Marine Corps’ operating forces consist of: 

w Marine Corps forces (MARFOR)

w Marine Corps security forces (MCSF) at

naval installations

w Marine security guard detachments at

embassies and consulates around the globe.

The “Forces for Unified Commands” memorandum

assigns Marine Corps operating forces to each of the

combatant commands. A force assigned or attached

to a combatant command may be transferred from

that command only as directed by the Secretary of

Defense and under procedures prescribed by the

Secretary of Defense and approved by the President.

The Marine Corps has established multiple Marine

Corps component headquarters to support the

unified commands.

a. Marine Corps forces are organized as MAGTFs

and are either employed as part of naval expeditionary forces or separately as part of larger joint or

combined forces. 

The commanders of MARFOR Atlantic and Pacific

serve as Marine Corps component commanders to

their respective combatant commanders and may

also serve as commanding generals of Fleet Marine

Forces (FMFs) Atlantic, Pacific, and Europe. As

commanding generals, with the status of a naval type

commander, they provide forces for service with

Commander US Atlantic Fleet, Commander US

Chapter 1

The Marine Corps
Pacific Fleet, and Commander US Naval Forces

Europe, respectively. (See figure 1-1.) 

The Marine Corps component commander deals

directly with the joint force commander (JFC) in

matters affecting assigned MARFOR. He

commands, trains, equips, and sustains MARFOR.

As such, he is responsible for:

w Making recommendations to the JFC on the

proper employment of Marine forces.

w Accomplishing such operational missions as

may be assigned.

w Selecting and nominating specific Marine

units or forces for assignment to other subordinate forces of the combatant command.

w Conducting joint training, including the training, as directed, of components of other

Services in joint operations for which the

Service component commander has or may

be assigned primary responsibility or for

which the Service component facilities and

capabilities are suitable.

w Informing the JFC (and the combatant

commander, if affected) of planning for

changes in logistic support that would significantly affect operational capability or sustainability sufficiently early in the planning

process for the JFC to evaluate the proposals before final decision or implementation. If

the combatant commander does not approve

the proposal and discrepancies cannot be

resolved between the combatant commander

and the Service component commander, the

combatant commander will forward the issue

through the Chairman of the Joint Chiefs of

Staff (JCS) to the Secretary of Defense for

resolution. Under crisis action or wartime

conditions, and where critical situations make

diversion of the normal logistic process

necessary, Service component commanders

will implement directives issued by the

combatant commander. 

w Developing program and budget requests

that comply with combatant commander

guidance on warfighting requirements and

priorities.

w Informing the combatant commander (and

any intermediate JFCs) of program and

budget decisions that may affect joint operation planning.

w Providing supporting operation and exercise

plans to support assigned missions.

Although there are five Marine Corps components,

there are only two Marine Corps component

commands. The Marine Corps has established two

combatant command-level Service component

commands: Marine Corps Forces, Atlantic, and

Marine Corps Forces, Pacific. The II Marine

Expeditionary Force is provided by Commander,

Marine Corps Forces, Atlantic, to the Commander in

Chief, U.S. Atlantic Command, and the I and III

Marine Expeditionary Forces are provided by

Commander, Marine Corps Forces, Pacific, to the

Commander in Chief, U.S. Pacific Command. This

assignment reflects the peacetime disposition of

Marine Corps forces. Marine expeditionary forces

are apportioned to the remaining geographic combatant commands for contingency planning and are

provided to the combatant commands when directed

by the Secretary of Defense.

The Commander, Marine Corps Forces, Atlantic, is

assigned to the Commander in Chief, U.S. Atlantic

Command, and the Commander, Marine Corps

Forces, Pacific, is assigned to the Commander in

Chief, U.S. Pacific Command. In order to provide

three-star, general officer representation to the

remaining three geographic combatant commands,

Commander, Marine Corps Forces, Atlantic

(COMMARFORLANT), is designated as the

Marine Corps component commander to both

Commander in Chief, U.S. European Command

(CINCUSEUCOM), and Commander in Chief,

U.S. Southern Command (CINCUSSOCOM). The

Commander, Marine Corps Forces, Pacific, is designated as the Marine Corps component commander

1-2 MCRP 5-12D
to the Commander in Chief, U.S. Central Command

(CINCUSCENTCOM).

Headquarters, Marine Corps Forces, Europe, has

been established in the European Command

(EUCOM) and a planning liaison element has been

established with both Central Command and Southern Command to support their respective designated

Marine Corps component commander. During

peacetime, the designated Marine Corps component

commander provides operation and contingency

planning support and advice to his respective

combatant commanders on Marine Corps-specific

matters. When directed, the Marine Corps component commander exercises operational control

(OPCON) of forces assigned or attached to the

combatant commander.

Additionally, Commander, Marine Corps Forces,

Pacific (COMMARFORPAC), possesses the

capability to deploy a combatant command-level

Marine Corps component headquarters. This

capability is required due to the unique nature of the

supported combatant commands.

b. The MCSF include approximately 3,400 Marines

who protect key naval installations and facilities

worldwide. Although not assigned to combatant

commands, they are part of the operating forces of

the Marine Corps. These security forces include

Marine barracks and Marine security force companies in the continental United States (CONUS) and

abroad, as well as Marine detachments afloat.

c. The Marine security guard battalion provides

forces to the Department of State for embassy

security. These Marines are currently assigned to

121 diplomatic posts in 115 countries throughout the

world. (See figures 1-2 and 1-3.)

1004. Marine Corps Forces Reserve

(MARFORRES)

a. The MARFORRES is a vital element of the

Marine Corps total force and is organized under the

Commander, Marine Corps Forces Reserve

(COMMARFORRES). (See figure 1-4.) It can

augment and reinforce any operations in which

MARFOR participate and contains some capabilities

that are not resident in the active forces, such as civil

affairs (CA) and graves registration. The Marine

Corps total force consists of the active component,

the Reserve component, and retired personnel.

Force expansion is made possible by the activation

of the MARFORRES, which, like the active forces,

consists of a combined-arms force with ground,

aviation, and CSS units. The Marine Corps Mobilization Management Plan (MPLAN), dated 7

November 1997, provides detailed guidance and

procedures for mobilizing/recalling members of the

Reserve. Graduated Mobilization Response (GMR)

is the ongoing process of providing a viable deterrent

capability to meet a crisis/contingency at the lowest

possible level and sequentially build a response force

that is appropriate to the threat. The President may

authorize recall of up to 200,000 Selected Reservists

(including individual mobilization augmentees

(IMAs)) to active duty for a period of 270 days.

Under this authority, Selected Marine Corps Reserve

(SMCR) units organized to serve as units must be

activated as units.

b. Organized under COMMARFORRES, the

MARFORRES includes the 4th Marine Division, the

4th Marine Air Wing (MAW), and the 4th Force

Service Support Group (FSSG). The subordinate

units of these commands are located at 191 training

centers in 46 states, Puerto Rico, and the District of

Columbia. COMMARFORRES provides SMCR

units and individual augmentees to the active duty

MARFOR when directed by the NCA through the

commandant of the Marine Corps. 

c. The MARFORRES is composed of the:

(1) Ready Reserve 

The Ready Reserve consists of those units and

members of a Reserve component who are liable for

active duty in time of war or national emergency as

proclaimed by the President or declared by

Congress or when otherwise authorized by law.

Included in the Ready Reserve are the SMCR and

the Individual Ready Reserve (IRR). 

(a) SMCR. The SMCR includes units and individual members who participate in scheduled drills and a

two-week annual active duty period for training

purposes (annual training duty).

(b) IRR. The IRR generally consists of Marines

who have recently served in the active forces or

Delayed Entry Program also belong to the IRR.

(2) Standby Reserve 

The Standby Reserve is composed of Marines not in

the Ready or Retired Reserve who are subject to

recall to active duty in time of war or a national

emergency as declared by Congress.

(3) Retired Reserve

The Retired Reserve includes reservists who are

retired under various laws and regulations. Retired

Reserves may be mobilized under conditions similar

to those for Standby Reserve mobilization.

d. Marine Expeditionary Force (MEF)

Augmentation Command Element (CE)

(MACE) 

Organized to support the MEF CE, a MACE

includes approximately 166 Reserve Marines who

are activated during a major theater war or any

contingency that may require additional support.

Both I MEF and II MEF have an assigned MACE.

The MACE provides additional personnel to all staff

sections, provides additional liaison officers, and

conducts command and control in rear area operations. 

1005. Supporting Establishment

The Marine Corps supporting establishment consists

of those personnel, bases, and activities that support

the Marine Corps operating forces. This infrastructure consists primarily of 16 major bases and stations

in the United States and Japan and all the personnel,

equipment, and facilities required to operate them.

This equates to approximately 30,000 Marines. The

supporting establishment also includes the Marine

Corps Recruiting Command, the Marine Corps

Combat Development Command and the Marine

Corps Systems Command, as well as all training

activities and formal schools. Additionally, the

supporting establishment includes those civilian activities and agencies that provide support to MARFOR.

In keeping with our expeditionary nature, these

installations that support the MEFs are strategically

located near air and sea ports of embarkation and

are serviced by major truck routes and rail heads to

allow for the rapid and efficient movement of

Marines and equipment. 

1006. Headquarters, U.S. Marine Corps

Headquarters, U.S. Marine Corps, consists of the

Commandant of the Marine Corps and those staff

agencies that advise and assist the Commandant in

discharging those responsibilities prescribed by law

and higher authority. The internal organization of

Headquarters, U.S. Marine Corps is described in the

Headquarters Marine Corps Organization

Manual.

The Commandant of the Marine Corps is directly

responsible to the Secretary of the Navy for the

administration, discipline, internal organization, training, requirements, efficiency, and readiness of the

Marine Corps; the operation of the Marine Corps

materiel support system; and the total performance of

the Marine Corps.

1-6 MCRP 5-12D
2001. General

The MAGTF is the Marine Corps’ principle organization

for the conduct of all missions across the range of military

operations. MAGTFs are balanced, combined-arms forces

with organic ground, aviation, and sustainment elements.

They are flexible, task-organized forces that can respond

rapidly to a contingency anywhere in the world and are able

to conduct a variety of missions. Although organized and

equipped to participate as part of naval expeditionary

forces, MAGTFs also have the capability to conduct

sustained operations ashore. The MAGTF provides a

combatant commander or other operational commander

with a versatile expeditionary force that is capable of

responding to a broad range of crisis and conflict situations.

MAGTFs are organized, trained, and equipped to perform

missions ranging from humanitarian assistance to

peacekeeping to intense combat and can operate in permissive, uncertain, and hostile environments. They may be

shore- or sea-based in support of joint and multinational

major operations and/or campaigns. MAGTFs deploy as

amphibious, air-contingency, or maritime prepositioning

forces (MPFs), either as part of a naval expeditionary force

or via strategic lift. They can present a minimal or a highly

visible presence and are able to project combat power

ashore in measured degrees or can provide secure staging

areas ashore for follow-on forces. MAGTFs are prepared

for immediate deployment overseas into austere operating

environments, bringing all means necessary to accomplish

the mission. When deployed aboard amphibious shipping,

MAGTFs maintain a continuous presence at strategic

locations around the globe and can be rapidly moved to and

indefinitely stationed at the scene of potential trouble. The

MAGTF provides the JFC with the capability of reconstitution, which is the ability of an expeditionary force to regenerate, reorganize, replenish, and reorient itself for a new

mission without having to return to its home base.

MAGTF operations are built on a foundation of six special

core competencies: expeditionary readiness,

c

ombined-arms operations, expeditionary operations,

seabased operations, forcible entry from the sea, and

Reserve integration.

To carry out their mission, MARFOR must be—

w Organized, trained, and equipped for combat essential to the prosecution of a naval campaign to seize

objectives against the best and most modern

equipped enemy.

w A balanced force of combined arms and services.

w Primarily trained, organized, and equipped for offensive employment.

w Adaptable to the active defense of advanced naval

bases.

w Trained, equipped, and ready for prompt and effective employment in any climate or terrain.

w Trained and equipped for airborne operations as

required, in accordance with policies and doctrines of

the JCS.

w Provided with sufficient organic CSS capability to

establish and sustain combat power in the execution

of normal missions and capable of supporting—

{ Supply.

{ Maintenance.

{ Transportation.

{ Deliberate engineering.

{ Services.

{ Health services.

w Provided with organic aviation units primarily organized, trained, and equipped to operate in conjunction

with ground units in amphibious operations and

capable of performing—

{ Offensive air support (OAS).

Chapter 2

Marine Air-Ground Task Forces
{ Antiair warfare (AW).

{ Assault support.

{ Air reconnaissance.

{ Electronic warfare (EW).

{ Control of aircraft and missiles.

Although MAGTFs are task organized, each MAGTF,

regardless of its size or mission, has the same basic structure.

Each MAGTF has four core elements: a CE, a ground

combat element (GCE), an aviation combat element (ACE),

and a CSS element (CSSE). (See figure 2-1.)

The CE is the MAGTF headquarters. It is task organized to

provide command and control capabilities (including intelligence and communications) necessary for effective planning,

direction, and execution of all operations.

The GCE is task organized to conduct ground operations in

support of the MAGTF mission. It is normally formed around

an infantry organization reinforced with requisite artillery,

reconnaissance, armor, and engineer forces and can vary in

size and composition from a rifle platoon to one or more

Marine divisions.

The ACE is task-organized to support the MAGTF mission

by performing some or all of the six functions of Marine

aviation. The ACE is normally built around an aviation

organization that is augmented with appropriate air command

and control, combat, combat support, and CSS units. The

ACE can operate effectively from ships, expeditionary

airfields, or austere forward operating sites and can readily

and routinely transition between sea bases and expeditionary

airfields without loss of capability. The ACE can vary in size

and composition from an aviation detachment with specific

capabilities to one or more MAWs.

The CSSE is task organized to provide the full range of CSS

functions and capabilities needed to support the continued

readiness and sustainability of the MAGTF as a whole. It is

formed around a CSS headquarters and may vary in size and

composition from a support detachment to one or more

Marine FSSG.

2002. Marine Expeditionary Force

The MEF is the principal Marine Corps warfighting organization. It is capable of missions across the range of military

operations, through amphibious assault and sustained

operations ashore in any environment. With appropriate

augmentation, the MEF CE is capable of performing as a

Figure 2-1. MAGTF Organization.

GCE ACE CSSE

CE
There are three standing MEFs: I Marine expeditionary

force (I MEF), based in southern California and Arizona; II

Marine expeditionary force (II MEF), based in North and

South Carolina; and III Marine Expeditionary Force (III

MEF), based in Japan and Hawaii. Each standing MEF

consists of a permanent CE and one Marine division,

MAW, and FSSG. (See figure 2-2.) These major

commands constitute the primary reservoir of combat

capabilities from which MAGTFs are sourced.

b. Concept of Employment

The size and composition of a deployed MEF can vary

greatly depending on the requirements of the mission. It can

deploy with not only its own units but also units from the

other standing MEFs, the Marine Corps Reserve, or the

other Services and the Special Operations Command. A

MEF typically deploys by echelon with 60 days of sustainment. The lead echelon of the MEF, tailored to meet the

specific mission, is designated the MEF (forward)

(MEF(FWD)) and may be commanded by the MEF

commander personally or by a designated commander. The

MEF(FWD) prepares for the subsequent arrival of the rest

of the MEF or other joint or combined forces. However,

the deployment of the MEF(FWD) does not necessarily

mean that all the forces of the standing MEF will follow. This

would occur only if the entire MEF were required. MEFs

may conduct sustained operations ashore upon completion

of an amphibious operation or by deploying from the sea,

land, or air and linking up with maritime prepositioning ships

carrying equipment and supplies. For additional information

concerning MPF operations refer to Marine Corps

warfighting publication (MCWP) 3-32, Maritime Prepositioning Force Operations (draft).

2003. Marine Expeditionary Unit (Special

Operations Capable)

The Marine expeditionary unit (special operations capable

(MEU (SOC)) is the standard forward-deployed Marine

expeditionary organization. (See figure 2-3.) Marine Corps

Forces Atlantic and Pacific maintain forward-deployed

MEUs (SOC) in the Mediterranean Sea, the western

Pacific, and the Indian Ocean or Arabian Gulf region. The

MEU (SOC) can be thought of both as a self-contained

Organization of Marine Corps Forces 2-3

operating force capable of missions of limited scope and

duration and as a forward-deployed extension of the

Marine expeditionary force.

MEUs routinely receive special training before deploying

that results in their being designated as “special operations

capable.” To receive the certification, the MEU undergoes

an intensive 26-week, standardized predeployment training

program that includes an exercise and a final evaluation. The

MEU must demonstrate competence across the entire

spectrum of required capabilities, be able to plan and

execute any assigned mission within six hours of notification,

and conduct multiple missions simultaneously. These MEUs

are augmented with selected personnel and equipment to

provide enhanced conventional and selected maritime

special operations capabilities.

a. Organization

There are seven standing MEU (SOC) CEs. Residing

within I MEF are the 11th, 13th, and 15th MEUs (SOC);

residing within II MEF are the 22nd, 24th, and 26th MEUs

(SOC); residing within III MEF is the 31st MEU(SOC).

Although each MEU (SOC) is task organized, a typical

MEU(SOC) includes—

w A standing CE.

w An infantry battalion reinforced with artillery, reconnaissance, engineer, armor, assault amphibian units,

and other detachments as required.

w A reinforced helicopter squadron with transport,

b. Concept of Employment

Embarked aboard a Navy amphibious ready group

(ARG), a deployed MEU (SOC) provides a combatant

commander or other operational commander with a quick,

sea-based reaction force for a wide variety of situations. In

many cases, the MEU (SOC) embarked on amphibious

shipping may be the first U.S. force at the scene of a crisis

and can conduct enabling actions for larger follow-on

forces. It can provide a visible and credible presence in

many potential trouble spots and can demonstrate the

United States’ willingness to protect its interests overseas.

The MEU(SOC) mission is to provide the NCA and the

combatant commanders with a forward deployed,

sea-based, rapid crisis response capability to execute a full

range of military operations. It is organized, trained, and

equipped as a self-sustaining, general-purpose expeditionary MAGTF that possesses the capability to conduct

operations across the spectrum of conflict, from military

operations other than war, to amphibious and other conventional operations in support of various contingency requirements, including selected maritime special operations such

as—

w Reconnaissance and surveillance.

w Specialized demolitions.

w Tactical recovery of aircraft and personnel (TRAP).

w Seizure/recovery of offshore energy facilities.

w Seizure/recovery of selected personnel or ma- teriel.

w Visit, board, search, and seizure of vessels.

w In-extremis hostage recovery.

2004. Special Purpose Marine AirGround Task Force

A special-purpose MAGTF (SPMAGTF) is a nonstanding

MAGTF temporarily formed to conduct a specific mission.

It is normally formed when a standing MAGTF is either

inappropriate or unavailable. SPMAGTFs are organized,

trained, and equipped to conduct a wide variety of missions

ranging from crisis response, to regionally focused training

exercises, to peacetime missions. Their SPMAGTF designation derives from the mission they are assigned, the

location in which they will operate, or the name of the

exercise in which they will participate (e.g., “SPMAGTF

(X),” “SPMAGTF Somalia,” “SPMAGTF UNITAS,”

“SPMAGTF Andrew,” etc.). 

a. Organization

An SPMAGTF may be any size, but normally it is the size

of a MEU (or smaller) with narrowly focused capabilities

chosen to accomplish a particular mission. It may be task

organized deliberately from the assets of a standing MEF,

or may be formed on a contingency basis from an alreadydeployed MAGTF to perform an independent, rapidresponse mission of limited scope and duration. By

definition, SPMAGTFs include all four of the basic elements

of a MAGTF.

b. Concept of Employment

SPMAGTFs are generally employed in the same manner as

a MEU. However, under certain circumstances they may

be deployed via commercial shipping or aircraft, strategic

airlift, or organic Marine aviation.

Organization of Marine Corps Forces 2-5
3101. General

The primary mission of Marine Corps aviation is to participate as the air component of the MAGTF in the seizure and

defense of advance naval bases and to conduct such land

operations as may be essential for the prosecution of a naval

campaign. A collateral mission is to participate as an integral

component of naval aviation in the execution of such other

Navy functions as the fleet commanders so direct.

3102. Expeditionary Aspects

Marine Corps aviation is organized, trained, and equipped

to function as the MAGTF ACE. The ACE must be

prepared to operate from a variety of sea- and shore-based

facilities (from naval shipping to austere forward operating

bases (FOBs)) to support MAGTF expeditionary operations. The focus of the ACE is to support the MAGTF

during the assault landing and subsequent operations ashore.

Initially, support could be furnished by Marine aircraft

squadrons operating from FOBs within striking distance of

the amphibious objective area or by V/STOL aircraft

operating from amphibious shipping.

3103. Functions

MAGTF aviation tasks are divided into six functional areas

that guide the commander in planning aviation allocation and

employment. The commander considers the functional area

to be used, rather than the specific means (individual

weapons system), for accomplishing the mission. Individual

weapons systems perform missions that are part of each

function of Marine aviation. The six functions of Marine

aviation are described in the following paragraphs.

a. OAS

OAS is “those air operations conducted against enemy

installations, facilities, and personnel to directly assist the

attainment of MAGTF objectives by the destruction of

enemy resources or the isolation of his military force.”

(MCRP 5-12C, Marine Corps Supplement to the DOD

Dictionary of Military and Associated Terms). OAS

includes the categories of close air support (CAS) and deep

air support (DAS).

(1) CAS. CAS is “air action by fixed- and rotary-wing

aircraft against hostile targets which are in close proximity to

friendly forces and which require detailed integration of each

air mission with the fire and movement of those forces.”

(Joint Pub 1-02, DOD Dictionary of Military and Associated Terms)

(2) DAS. DAS is “air action against enemy targets at such

a distance from friendly forces that detailed integration of

each mission with fire and movement of friendly forces is not

required. Deep air support missions are flown on either side

of the fire support coordination line; the lack of a requirement for close coordination with the fire and movement of

friendly forces is the qualifying factor.” (MCRP 5-12C).

DAS missions include strike coordination, air interdiction,

and armed reconnaissance.

b. Antiair Warfare 

AAW is “that action required to destroy or reduce to an

acceptable level the enemy air and missile threat. It includes

such measures as the use of interceptors, bombers, antiaircraft guns, surface-to-air and air-to-air missiles, electronic

attack, and destruction of the air or missile threat both

before and after it is launched. Other measures which are

taken to minimize the effects of hostile air action are cover,

concealment, dispersion, deception (including electronic),

and mobility.” (Joint Pub 1-02) The primary purpose of

AAW is to gain and maintain some degree of air superiority.

Chapter 3

Marine Aircraft Wings

Section I. Fundamentals
AAW includes both offensive and defensive means to

accomplish its objective.

(1) Offensive AAW.Offensive AAW constitutes

operations conducted against the enemy air or air defense

system before it can be launched or assume an attacking

role. Offensive AAW operations in or near the objective

area consist mainly of air attacks to destroy or neutralize

hostile aircraft, airfields, radars, air defense systems, and

supporting areas. Offensive AAW includes theater missile

defense (TMD) attack operations and suppression of

enemy air defense operations.

(2) Air Defense.Air defense includes alldefensive

measures designed to destroy attacking enemy aircraft or

missiles in the earth’s atmosphere or to nullify or reduce the

effectiveness of such attack. There are two forms of air

defense: active and passive. 

(a) Active air defense is direct defensive action taken to

destroy attacking enemy aircraft or missiles or to nullify or

reduce the effectiveness of such an attack. Active air

defense includes the use of aircraft, air defense weapons,

supporting weapons (weapons not typically used in an air

defense role), and EW.

(b) Passive air defense constitutes all measures, other than

active defense, taken to minimize the effects of hostile air

action. These include the use of cover, concealment,

camouflage, deception, dispersion, electronic protection,

and protective construction. Passive air defense is a

command responsibility of every unit commander.

c. Assault Support

Assault support is “the use of aircraft to provide tactical

mobility and logistic support for the MAGTF, the

movement of high priority cargo and personnel within the

immediate area of operations, in-flight refueling, and the

evacuation of personnel and cargo.” (Fleet Marine Force

manual (FMFM) 5-30, Assault Support) The tasks of

assault support fall within the following seven categories: 

(1) Combat assault transport provides mobility and logistic

support to the MAGTF. It can be used to rapidly deploy

forces, bypass obstacles, or redeploy forces to meet the

enemy threat, thus allowing for a rapid buildup of combat

power at a specific time and location.

(2) Aerial delivery operations transport equipment and

supplies to FOBs or remote areas either by landing at the

desired location or through air drop.

(3) Aerial refueling allows MAGTF aircraft to conduct

flight-ferrying operations, extend time on station, and extend

mission range. In addition, aerial refueling aids in the recovery of damaged or low-fuel aircraft by extending their time in

the air, when required.

(4) Air evacuation provides transportation of personnel and

equipment from FOBs or remote areas by using transport

helicopters and fixed-wing aircraft. 

(5) TRAP facilitates the recovery of personnel and equipment while preventing additional loss. The TRAP mission is

an implied task associated with all MAGTF operations.

Specially briefed aircrews are assigned to perform TRAP

missions. TRAP missions are conducted when the tactical

situation prevents the use of traditional search and reserve

techniques. TRAP is normally conducted only when survivors and their locations are confirmed.

(6) Air logistical support operations are conducted by using

fixed-wing aircraft to provide assault support of MAGTF

forces on the ground in much the same manner as helicopters. Air logistical support delivers troops, equipment, and

supplies to areas beyond helicopter range and lift capability

or when surface transportation is slow or unavailable.

(7) Battlespace illumination can be provided by both fixedand rotary-wing aircraft and is used to provide light in the

battlespace area.

d. Air Reconnaissance

Air reconnaissance is “the acquisition of intelligence information by employing visual observation and/or sensors in air

vehicles.” (FMFM 5-10, Air Recon- naissance)

(1) Visual Reconnaissance. Any airborne platform

may conduct visual aerial reconnaissance operations. An

observer or pilot can visually search a route, point, or area.

Visual aerial reconnaissance is frequently related to offensive

action such as artillery, naval surface fires (NSF), or air

support.

(2) Multisensor Imagery Reconnaissance.

Multisensor imagery reconnaissance includes photographic,

side-looking airborne radar, and infrared reconnaissance

3-2 MCRP 5-12D
techniques. When the imagery is processed, it provides

intelligence information to all interested commands.

(3) Electronic Reconnaissance.EW-configured

aircraft provide the means to detect, identify, evaluate, and

locate foreign electromagnetic radiation that is emanating

from other-than-nuclear detonations or radioactive sources,

thereby providing up-to-date electronic order of battle and

technical intelligence.

e. EW

EW is “any military action involving the use of electromagnetic and directed energy to control the electromagnetic

spectrum or to attack the enemy.” (Joint Pub 1-02) The

three major subdivisions of EW are electronic attack (EA),

electronic protection, and EW sup- port.

(1) EAis “that division of electronic warfare involving the

use of electromagnetic, directed energy, or antiradiation

weapons to attack personnel, facilities, or equipment with

the intent of degrading, neutralizing, or destroying enemy

combat capability.” (Joint Pub 1-02)

(2) Electronic protection involves “actions taken to protect

personnel, facilities, and equipment from any effects of

friendly or enemy employment of electronic warfare that

degrade, neutralize, or destroy friendly combat capability.”

(Joint Pub 1-02)

(3) EW supportinvolves “actions tasked by, or under

direct control of, an operational commander to search for,

intercept, identify, and locate sources of intentional and

unintentional radiated electromagnetic energy for the

purpose of immediate threat recognition.” (Joint Pub 1-02)

f. Control of Aircraft and Missiles

The control of aircraft and missiles involves the coordinated employment of facilities, equipment, communications, procedures, and personnel that allows the ACE

commander to plan, direct, and control the efforts of the

ACE to support accomplishment of the MAGTF’s mission.

Control of aircraft and missiles is executed through the

Marine Air Command and Control System (MACCS).

The control of aircraft and missiles function serves to

integrate the activities of the other five functions of Marine

aviation into a coordinated effort.

3104. Marine Aviation Organization

Organizationally, Marine aviation is divided into three active

duty MAWs and one Reserve MAW. Each MAW has a

unique organizational structure; these structures are represented in figure 3-1 on page 3-4, figure 3-2 on page 3-5,

figure 3-3 on page 3-6, and figure 3-4 on page 3-7. The

MAW provides the personnel and equipment for the

MAGTF ACE. Operationally, the ACE task organizes with

various resources from the MAW that are necessary to

complete the ACE’s assigned mission. 

Typically, the ACE supports a MEF with one or more

MAWs. Support to the MEF may include assets from

more than one MAW that are task organized to form a

MAW (reinforced). The ACE supports a MEU with a

task-organized squadron that usually consists of a mix of

rotary-wing aircraft, short take-off and landing aircraft, a

Marine air control group (MACG) detachment, a fixedwing Marine aviation logistics squadron (MALS) detachment, and a rotary-wing MALS detachment. The ACE

normally supports an SPMAGTF with a task-organized

squadron that consists of a mix of rotary-wing aircraft, short

take-off and landing aircraft, a MACG detachment, a fixedwing MALS detachment, and a rotary-wing MALS

detachment. Actual squadron composition will depend on

mission requirements.

MAWs include Marine aircraft, air control, and wing

support groups. Each group includes the squadrons and/or

battalions that are necessary to complete the groups’ roles in

Marine aviation. MAWs and groups are not organized

according to tables of organization (T/Os), but rather are

task organized to accomplish the missions assigned. Each of

the four wings may have a different organization; however,

each wing is capable of performing all six functions of

Marine aviation.

3201. General

The notional MAW is task organized to provide a flexible

and balanced aviation organization that is capable of providing the full range of aviation operations in a variety of areas

without the requirement for prepositioned support, control,

and logistical facilities. The MAW is the smallest unit with

the inherent capability of performing all six functions of

Marine aviation. The wing is composed of the subordinate

units depicted in figure 3-5. Aviation organizations smaller

than a wing can provide the capabilities to accomplish any

or all aviation functions by using task organization.

4003. Infantry Regiment, Marine Division

a. Mission

The primary mission of the infantry regiment is to locate,

close with, and destroy the enemy by fire and maneuver or

to repel his assault by fire and close combat.

b. Concept of Organization

The infantry regiment consists of a headquarters company

and two or more infantry battalions (normally three infantry

battalions). (See figure 4-3.) The infantry battalions are the

basic tactical units with which the regiment accomplishes its

mission. The headquarters company of the infantry regiment

contains a regimental headquarters and a reconnaissance

platoon. When combined with other combat support and

CSS units, it will form a regimental landing team. Command

and staff functions for the regiment are exercised through a

compact operational command group that consists of the

commander and an executive staff. The staff is capable of

integrating the efforts of attached units with those of supporting units. The staff can support a tactical, main, and rear

command echelon during displacement. The basic means of

ground mobility of the regiment is by foot, supplemented by

(1) Infantry Battalion. The infantry battalion consists of

an H&S company, a weapons company, and three rifle

companies. (See figure 4-6 on page 4-6, figure 4-7 on page

4-7, and figure 4-8 on page 4-7.) The rifle companies are

the basic tactical units with which the battalion accomplishes

its mission. When the battalion is combined with combat

support and CSS units, it forms a battalion landing team

(BLT).

(2) Command and Staff Functions. Command and

staff functions are exercised through a compact operational

command group that consists of the commander and his

executive staff. The staff is capable of integrating the efforts

of attached units with those of supporting units by using

representatives of these elements provided for that purpose.

The staff is capable of supporting a tactical and main

echelon and alternatives during displacement. All fire in

support of the battalion is coordinated by the weapons

company commander, who functions as the battalion fire

support coordinator under the staff cognizance of the

operations officer.

(3) Battalion Firepower. In addition to individual

weapons, the organic battalion firepower consists of light,

medium, and heavy machine guns; light and medium

mortars; and light and medium antiarmor weapons that are

capable of supporting the rifle companies.

(4) Mobility. The basic means of mobility is by foot,

supplemented by use of organic, small, lightweight vehicles

for the transportation of electronics equipment, weapons,

and limited amounts of ammunition and supplies. All

elements are helicopter transportable and are compatible

with other means of transportation (e.g., AAVs, motor

transport, fixed-wing aircraft, and ships).

(5) Logistic Capability. Logistic capability is compatible

with the mobility and combat power of the battalion. The

battalion is structured on the basis of unit distribution of

supplies within the battalion.

(6) Total Weapons in the Infantry Battalion. For a

complete list of infantry battalion weapons, see table 4-2.

(7) Weapon Distribution. Within the rifle company, the

fire team leader carries an M16A2 rifle and an M203

grenade launcher. The squad automatic rifleman carries the

M249 squad automatic weapon (SAW); all other riflemen,

including the assistant automatic rifleman, carry an M16A2.

Squad leaders and the officers and enlisted personnel of the

platoon headquarters carry M16A2 rifles.

The weapons platoon machine gun section has six M240G

machine guns, the mortar section has three M224 60-mm

mortars, and the assault section has six MK153 83-mm

The heavy machine gun platoon has six each of M2 .50-cal

machine guns and MK19 40-mm grenade machine guns.

c. Concept of Employment

The battalion is the basic tactical unit of ground combat

power and the nucleus of the BLT. As a balanced

firepower and maneuver team, it attacks and destroys all

targets in the assigned area of responsibility. With detachments, it is capable of independent, sustained operations for

a period of several days as permitted by combat conditions.

It is capable of conducting a coordinated deliberate defense.

d. Logistic Capabilities

For information on logistic capabilities, see paragraph

4003.d. For selected items of equipment, see table 4-1 on

4005. Artillery Regiment, Marine Division

a. Mission

The mission of artillery in the Marine division is to furnish

close and continuous fire support by neutralizing, destroying,

or suppressing targets that threaten the success of the

supported unit.

b. Concept of Organization

All artillery regiments have a headquarters battery. There are

four artillery battalions in the 10th and 11th Marine

Regiments and two in the 12th Marine Regiment. (See

figure 4-9.) Each of these battalions is capable of performing

the responsibilities associated with any of the four standard

artillery tactical missions. Artillery regimental functions are

discharged through a command group, which consists of the

commander and executive staff, augmented by sufficient

technical personnel. The staff is capable of integrating the

efforts of any attached, reinforcing, or supporting units. The

staff is capable of supporting a tactical, main, and rear

command echelon during displacements and, when

augmented, can operate as an alternate division COC for

short periods of time. The basic means of ground mobility is

organic vehicular transportation. All CEs and some fire

support assets are helicopter transportable. With the M198

weapons system, helicopterborne mobility is severely

limited.

c. Concept of Employment

The artillery regiment is the primary source of fire support

for the Marine division. Its operations and actions are

closely integrated with those of the infantry to be responsive

to rapidly changing tactical situations. The artillery regiment

provides a fire support coordination section to assist in

establishing and operating an FSCC at the division COC.

d. Target Acquisition

Each regiment is equipped with a counterbattery radar

platoon that is capable of locating enemy indirect-fire

weapons within the division’s sector. The platoon has five

AN/TPQ-46Acounterbatteryradars.

e. Logistic Capabilities

The logistic capabilities that follow cover the capabilities of

the headquarters battery, the artillery regiment, and the

individual artillery battalions. The total logistic capability of

the regiment is the sum of the capabilities of its subordinate

units.

(1) Administrative Capabilities. The artillery regiment

is capable of self-administration.

(2) Maintenance. The artillery regiment performs organizational (1st and 2d echelon) maintenance on all equipment

(except fire control). The headquarters battery of the artillery

regiment performs intermediate (3d and 4th echelon)

maintenance on electronics systems within the command

and performs intermediate (4th echelon) maintenance on

weapons-loading radar equipment.

(3) Supply. Artillery units perform all supply functions to

some degree. Supply operations are performed in each

class of supply, with particular emphasis on classes I, III, V,

and IX. External supply support is obtained from the

CSSE.

(4) Health Services. Medical personnel provide

emergency treatment and preparation for evacuation of all

casualties, treat minor illnesses and injuries, and supervise

disease prevention and control measures.

(5) Transportation. The organic transportation assets of

the artillery unit provide the necessary mobility to deliver

continuous artillery support. Artillery units are capable of

moving their personnel, equipment, and a limited quantity of

supplies. Organic vehicles consist of wheeled vehicles. Artillery is capable of being transported by landing craft, transport aircraft, and, to a limited extent, helicopters.

(6) Messing. The headquarters battery is capable of

operating a battery mess hall. The battalions can operate a

battalion mess hall.

(7) Selected Items of Equipment.The composition

of artillery battalions varies in I, II, and III MEF. The equipment list in table 4-3 is provided for planning purposes and

is divided by the type of battery that the equipment

supports. For a list of equipment for a specific unit, refer to

the appropriate T/E.

4006. Artillery Battalion, Artillery Regiment

a. Mission

The mission of the artillery battalion in the Marine division is

to furnish close and continuous fire support by neutralizing,

destroying, or suppressing targets that threaten the success

of the supported unit.

b. Concept of Organization

An artillery battalion consists of a headquarters battery and

firing batteries. The headquarters battery provides the

equipment and personnel to assist the battalion commander

in controlling and supporting his battalion. Like the regiment,

the battalion headquarters may be employed in a main or

rear echelon configuration. Artillery battalions have three or

four firing batteries of six howitzers. Marine artillery currently

employs the M198, 155mm towed howitzer.

c. Concept of Employment

The artillery battalion is the basic tactical unit of the artillery.

It has enough firing units to effectively mass its fires and to

engage several targets simultaneously. The battalion is

normally employed as a unit to meet the fire support

requirements that are defined by its assigned tactical mission.

The battalion maintains communications with its batteries

and any attachments, the supported/reinforced units, and the

artillery regiment as appropriate. When a battalion deploys

4-10 MCRP 5-12D
independently, it is augmented with appropriate support

from the regiment; for example, the meteorological section.

d. Logistic Capabilities

For logistic capabilities, see paragraph 4005.e.

4007. Tank Battalion, Marine Division

a. Mission

The mission of the tank battalion is to close with and destroy

the enemy by using armor-protected firepower, shock

effect, and maneuver and to provide antimechanized fire in

support of the Marine division.

b. Concept of Organization

A typical tank battalion consists of an H&S company, one

antitank platoon, and four tank companies. The tank

companies are the basic tactical unit with which the battalion

accomplishes its mission. The antitank platoon provides

antimechanized support to the division. (See figure 4-10 on

page 4-12.) The tank battalion has 58 M1A1 tanks (with

120-mm guns), 26 TOW weapons systems, and 5 M88A1

tank recovery vehicles.

c. Concept of Employment

The battalion is best employed as a maneuver force without

detaching units. However, the division commander may

task organize forces of tanks, mechanized infantry, and

other division resources based on mission, enemy, terrain

and weather, troops and support available-time available

(METT-T) that require cross-attachment of tank battalion

and infantry regiment assets. Employment of the tank battalion must take advantage of the speed, mobility, and

firepower of the organization.

(3) Communications.Communications support is

provided by the H&S company of the combat engineer

battalion.

(4) Mobility. The company possesses a limited amount of

helicopter-transportable equipment. It requires heavy motor

transport support to displace its various platoons and/or

squads. When augmented with vehicles from the engineer

support company, the combat engineer company can

achieve mobility that is compatible with the support unit

except in mechanized operations. In this case, it then

becomes the responsibility of the support unit to allot sufficient space in its combat vehicles to provide comparable

engineer mobility.

c. Concept of Employment

A combat engineer company is generally in direct support of

an infantry regiment for operations. Although the company

may operate under the centralized control of the company

commander, it may more frequently operate under the

control of the platoon leaders in widely dispersed areas,

with the company commander acting as advisor to the

infantry regimental commander. One combat engineer

company is provided for support of division elements to the

rear of forward areas and to augment the engineer companies in forward areas, as required. The combat engineer

company has limited construction equipment, some of

which is helicopter transportable. Equipment augmentation

with operators is furnished as necessary from the engineer

support company. In all such cases, control of augmenting

elements is generally passed to the combat engineer

company requiring such assistance.

5001. General

The FSSG is a composite grouping of functional components that provides CSS above the organic capability of

supported units to all elements of the MEF. In this respect, it

is structured to support, in garrison or deployed, a

one-division/one-wing-configured MEF. All elements of the

FSSG are structured to provide permanently organized

subelements to support independently deployed battalions,

regiments, MEUs (i.e., task-organized groups to provide

support, as required and preplanned), or geographically

separated units in gar- rison.

The most significant attribute of the FSSG is that it is a

permanently organized command charged with the responsibility of providing all major CSS functions for the MEF

beyond the organic capabilities of the supported

units/organizations. Thus, it is staffed and equipped by T/Os

and T/Es to support a one-divi- sion/one-wingMEF or four

MEUs simultaneously.

The FSSG embodies a fundamental principle—economy of

operations through centralization of CSS resources and

decentralization in executing CSS tasks—in a conscious

effort to attain efficient use of these scarce resources

(personnel, supplies, and equipment) and a rational, aggressive assignment of work priorities. The FSSG commander,

through his staff and by a coordinated, mutual exchange of

operational information with supported MAGTF organizational/ unit commanders, tailors each FSSG organization to

meet specific preplanned requirements. Task-orga- nized

CSSEs, in support of deployed forces, provide the FSSG

commander, his staff, and other CSS planners with operational and historical data on which to base future planning by

means of narrative and statistical reports.

5002. Force Service Support Group

Command Element

a. Mission

The FSSG CE provides general and direct support and

sustained CSS above the organic capabilities of supported

elements of MAGTFs in the functional areas of CSS during

deployment and employment of the MEF and smaller,

geographically separated MAGTFs in all levels of conflict.

b. Tasks

w Provide centralized ground supply support, beyond

supported units’ organic capabilities, for the sustainment of the MEF, including procurement, storage,

care in storage, distribution, salvage, disposal, and

bulk fuel and water supply support.

w Provide authorized overflow organizational (2d

echelon) and intermediate (3d and 4th echelon)

maintenance support, beyond supported units’

organic capabilities, for Marine Corps-furnish- ed

ground equipment of the MEF, including inspection,

classification, servicing, adjustment, tuning, testing,

calibration, repair, modification, rebuilding overhaul,

reclamation, recovery assistance, and evacuation. 

w Coordinate transportation and throughput support,

beyond supported units’ organic capabilities, for the

deployment and employment of the MEF, including

embarkation, landing support, port and terminal

operations, motor transport, air delivery, and

freight/passenger transportation support.

w Provide general engineering support to the MEF,

including engineering reconnaissance; horizontal

construction of roads, CSS installations, and other

support facilities; vertical construction and maintenance of encampment and other personnel support

facilities; emplacement of standard and nonstandard

bridging and rafting; demolition and obstacle

Chapter 5

Marine Force Service Support Groups
removal; augmentation for tasks beyond the organic

engineering capabilities of supported units; and

explosive ordnance disposal (EOD).

w Provide health service (medical and dental) support,

beyond the supported units’ organic capabilities, to

the MEF, including health maintenance, patient

collection and treatment, temporary hospitalization,

patient regulation and evacuation, disease control,

hygienic services, and a comprehensive dental

program.

w Coordinate services support, beyond supported

units’ organic capabilities for the MEF, including

security support, postal, disbursing, and exchange

services; legal services (including active duty nucleus

capability for CA); CSS-related CA support; and

graves registration.

c. Concept of Organization

The FSSG is a permanently structured command that

constitutes the CSSE of the MEF. When manned and

equipped at full T/O and T/E levels, the FSSG can support

a MEF, or four MEUs simultaneously, or a combination of

various smaller CSSEs, MEU service support groups

(MSSGs), or CSSDs in support of MAGTF operations

below MEF level. It is capable of providing the CE nucleus

for three MSSGs/CSSEs to support MAGTFs. The

FSSG includes an H&S battalion for command and control

and seven permanently organized battalions that provide

logistics and CSS along functional area lines. Similar

functions are generally centralized at the battalion level to

facilitate command and control, coordination of taskings and

training, and maintenance of equipment. Within the limits of

their capabilities, each battalion provides personnel and

equipment to source task-organized CSSEs that are established to support MAGTFs. See figures 5-1a, 5-1b, 5-1c,

and 5-1d.

(1) Command and Control. The FSSG commander

exercises command and control of the FSSG through the

general/special staff and subordinate commanders by using

organic communications assets. This system permits the

FSSG commander to structure organizations, assign appropriate missions and tasks, and establish appropriate

command relationships that enhance efforts to achieve

centralized control while facilitating decentralized execution

of CSS tasks. When required, the FSSG commander task

organizes CSSEs from the assets of the functional battalions.

(3) Mobility.Organic medium- and heavy-lift vehicles can

displace the FSSG in echelons. Use of organic transportation to move the FSSG degrades its ability to provide simultaneous transportation support to the MEF.

(4) Communications. The FSSG possesses sufficient

organic communications capabilities to install, operate, and

maintain communications systems for internal and limited

external communications require- ments.

(5) Intelligence.The organic intelligence gathering and

processing capabilities of the FSSG are limited. They

include limited tactical and logistical intelligence support for

the FSSG CE and organic battalions.

(6) Security.The FSSG is responsible for the local

security of established CSS installations against ground

attack and employs passive defense measures against other

forms of attack. When tasked by the MEF commander, it

also coordinates security within the MEF rear area. Antiair

and antimechanized rear area security requirements must be

satisfied by other elements of the MEF. Within its capability,

the FSSG provides security for lines of communications in

the MEF rear area used by the FSSG in transporting

supplies, equipment, and personnel. It coordinates security

requirements with supported units for such movements

within the supported units’ areas of responsibility.

d. Concept of Employment

The FSSG provides sustained CSS to each element of the

MEF in the functional areas of CSS beyond the organic

capabilities of supported units. It provides CSSEs to smaller

MAGTFs that may be permanently organized or task

organized for specific missions. When supporting a taskorganized force that is greater than the combined assets of

one division and one aircraft wing, the FSSG may require

augmentation for requirements beyond its organic capabilities. To provide the necessary throughput support to the

MEF, the FSSG establishes, as required, beach support

areas, landing zone support areas, CSS areas (CSSAs), a

force CSSA (FCSSA), and other CSS installations

commensurate with the level of operations to ensure

responsive, timely support for the sustainment of the MEF.

e. Administrative Capability

Each organic battalion and CSSD CE nucleus is capable of

self-administration.

f. Logistic Capabilities

(1) Supply. The FSSG is capable of organic supply

support. It provides selected consumer-level and full

intermediate-level ground supply support, including class I

subsistence supply support to the MEF and other FMF

units, as required.

(2) Maintenance.The FSSG is capable of organizational and intermediate-level (1st through 4th echelon)

maintenance on organic equipment. It provides general

support intermediate maintenance (3d and 4th echelons) on

Marine Corps-furnished ground equipment to other units of

the MEF for those units not authorized those levels of

maintenance and, when performance of authorizedmaintenance exceeds supported units’ capability, overflow organizational (2d echelon) main- tenance.

(3) Transportation. The FSSG is capable of organic

transportation support. It provides medium- and heavy-lift

motor transport support and coordinates the movements of

elements of the MEF to, from, and through ports of embarkation and debarkation.

(4) General Engineering.The FSSG is capable of

general support engineering support to organic FSSG and

supported MEF units that require EOD support and intensive engineering efforts involving detailed planning and

preparation to meet standards, design, and construction

criteria beyond the organic capabilities of supported units.

(5) Health Services.The FSSG is capable of providing

medical and dental support to organic battalions and other

units of the MEF when those units’ needs exceed their

organic capabilities.

(6) Services. The FSSG is capable of services support

to organic FSSG units and supported MEF units in the

functional areas of security support, disbursing, postal, and

exchange services; logistic information systems; legal

services support; CA support; and graves registration.

5-4 MCRP 5-12D
(7) Messing. The FSSG is capable of organic food

service support.

with necessary augmentation from supported units

as required.

c. Concept of Organization

The battalion is organized to provide command, control,

and command support functions for the FSSG and its H&S

battalion and to provide appropriate support in CSS

functional areas for the deployment/employ- ment of the

MEF or the simultaneous deployment/em- ployment of two

brigade service support groups(BSSGs) and the remaining

FSSG elements. (See figure 5-2 on page 5-6.)

(1) Command and Control.The battalion

commander exercises command and control through the

battalion staff and subordinate company commanders. He

directs and controls command support functions relating to

operations, administration, and logistics/CSS for the battalion. The command structure and centralization of services

support functions in the H&S battalion permit the battalion

commander to coordinate services support tasks assigned

to the battalion and to plan and structure appropriate

CSSEs for MAGTF deployments.

(2) Firepower.Organic firepower capability is limited to

individual and crew-served weapons for personal and local

security.

Organization of Marine Corps Forces 5-5
(3) Mobility.Organizational vehicles of the battalion

FSSG headquarters.

(6) Security. The H&S battalion is responsible for the

local security of CSS installations established within its area

of responsibility against ground attack and employs passive

defense measures against other forms of attack. Antiair and

antimechanized rear area security requirements must be

satisfied by other elements of the MAGTF. Within its

capability, the H&S battalion provides security for lines of

communications in the MAGTF rear area used by the

FSSG in transporting supplies, equipment, and personnel. It

coordinates security requirements with supported units for

such movements within the supported units’ areas of

responsibility.

d. Concept of Employment

The H&S battalion provides, under a single servicesoriented commander, the command and control organization to achieve an integration of capabilities that are essential

to the services support requirements of the MEF and the

FSSG. Subordinate units of the battalion, under the centralized control of the battalion commander, are capable of

responsive, adaptable task organization to meet the particular support requirements to establish and sustain the relative

combat power of the MEF and/or MAGTFs smaller than a

MEF.

e. Administrative Capability

deployed as a battalion, the structure supports MAGTF

operations through detachments composed of platoons

from each of the functional companies; these platoons are

task organized to provide the full range and depth of intermediate (3d and 4th echelon) maintenance. The detachments are assigned to the supporting CSSE. Depending on

the tactical situation, decentralized execution of maintenance

support is provided through task-oriented maintenance

support teams that can provide on-site repair support.

When maintenance needs exceed the capability of the

maintenance support teams, unserviceable components

normally are evacuated to the rear for rebuilding at an established CSSA or repair facility. The battalion (-) provides

(6) Security. The battalion has a limited organic security

capability. Security support, as required, is provided by the

H&S battalion.

d. Concept of Employment

The battalion units are task organized to support the mobility

and flexibility requirements of the MAGTFs. The medical

battalion constitutes appropriately sized and configured

medical treatment facilities in support of specific MAGTFs.

(1) Shock-Trauma Platoons, H&S Company.

The shock-trauma platoons are the most mobile of the

medical battalion units. They are designed to provide direct

support to medical elements organic to the GCE and ACE

of a MAGTF. Where required by the operational plan,

shock-trauma platoons lend themselves to being task

organized for support of MEU- and MEF(FWD)-sized

MAGTFs. They may be combined or collocated to

increase their own capabilities and the care provided to

Marines or to relieve a battalion aid station (BAS) of its

patients, thereby allowing the BAS to follow in trace of its

CE or act as the advance element for the location of a surgical company. One way in which a shock-trauma platoon

may be employed is as part of a mobile CSSD.

(2) Surgical Company. By virtue of its larger size, a

fully deployed surgical company is best suited for a general

support role from a location less likely to require displacement and relocation. However, the surgical company structure and organization lends itself to dividing into independent

elements for deployment and therefore can also be used to

provide direct support to operating forces through the use of

shock-trauma platoons. For example, the triage/evacuation

platoon of a company may be deployed with the AE of a

combat force, while the holding and surgical platoons are

placed in the AFOE. Once ashore, the remaining units of

the surgical company may join the triage/evacuation platoon,

or the company may establish itself in a different location.

(3) Levels of Patient Care.Shock-trauma platoons

provide echelon I-level care, and the surgical company

provides echelon II-level care. Shock-trauma platoons

provide the emergency stabilization care required for

evacuation. The capabilities of the surgical company are built

around the surgeons contained in its T/O. If tactical situations dictate, a shock-trauma platoon could be augmented

with a section from the surgical company to provide a

forward surgical capability.

e. Administrative Capability

The medical battalion is capable of self-administration for

assigned Marine Corps personnel. Administrative support

for assigned U.S. Navy personnel is provided by the service

company of the H&S battalion.

f. Logistic Capabilities

(1) Supply. The battalion is capable of organic supply

support. The medical logistics company of the supply battalion provides class VIII supply support.

(2) Maintenance.The battalion is capable of organizational (1st echelon) maintenance on organic equipment and

organizational (2d echelon) maintenance on organic equipment, except for medical equipment. The medical logistics

company of the supply battalion provides organizational (2d

echelon) and intermediate (3d and 4th echelon) maintenance support for medical equipment and maintains the

AMALs. Intermediate (3d and 4th echelon) maintenance

support for nonmedical equipment is provided by the

maintenance battalion.

(3) Transportation. The battalion is capable of organic

transportation for command and administrative purposes

and for evacuation of casualties from forward areas and

transfer of patients to medical treatment facilities in rear

areas.

(4) General Engineering. Engineering support, as

required, is provided by the engineer support battalion.

(5) Health Services. The battalion is capable of organic

medical support. Routine sick-call support is provided by

the group aid station of the H&S battalion, and dental

support is provided by the dental battalion.

(6) Services. Services support, as required, is provided

by the service company of the H&S battalion.

(7) Messing. The battalion is capable of organic food

service support. When collocated with the dental battalion,

the medical battalion provides consolidated food service

d. Concept of Employment

An entire surgical company is structured to facilitate task

organization for operations conducted by the battalion in

support of the MEF(FWD), MEF, or any combination of

larger MAGTFs. The surgical company is designed to allow

a high degree of mobility and flexibility in deployment. A

surgical company may be divided into smaller elements

(sections) to task organize the support. This facilitates

deploying a platoon or section in the AE and the remaining

capability in the AFOE shipping. In a displacement and

relocation evolution, it may be expedient to move platoons

and sections in a leapfrog fashion to provide maximum

continuity of patient care. A surgical section may augment

the medical facility of an MWSS, bringing surgical capability

to that facility. It is also suited for augmenting a shocktrauma platoon when operational conditions permit.

w Provide and coordinate medical evacuation.

w Provide medical support to personnel of other

Services and nations as provided in applicable

regulations and agreements and provide humanitarian care as required by international law.

c. Concept of Organization

The shock-trauma platoon is the smallest mobile medical

support element of the medical battalion and is the first

medical treatment facility of the MAGTF in support of the

BAS. The eight shock-trauma platoons are structured to

facilitate task organization for operations conducted by the

battalion in support of the MEF, the MEF(FWD), or any

combination of smaller MAGTFs. The platoon consists of a

stabilization section and a collecting and evacuation section.

(See figure 5-37.) Each collecting and evacuation section

has two tactical ambulances for collecting casualties from the

next forward medical support echelon, and the stabilization

section has 5-ton trucks to move the shock-trauma platoon

personnel and equipment.

Organization of Marine Corps Forces 5-79
6001. General

This chapter addresses MAGTF command elements (CE)

and units that are not subordinate to either the Marine

division, the MAW, or the FSSG.

6002. Marine Expeditionary Force

Command Element

a. Mission

To provide command and control of the Marine Expeditionary Force (MEF). The MEF Command Element (CE) is

responsible for the command, control, direction, planning

and coordination of corps-level air, ground, and logistical

operations of assigned forces, normally consisting of one or

more Marine divisions, Marine aircraft wings, and force

service support groups, and other separate units. 

b. Tasks

The MEF CE performs the following general functions:

w Exercises tactical direction over units assigned by the

Marine component, FMF commander, naval

component commander, or a joint force commander

(JFC).

w Coordinate and conduct the deep, close, and rear

battles throughout its designated area of oper- ations.

w Determine the detailed composition of the force.

w Develop overall tactical plans for command and

control, intelligence, maneuver, fires, logistics and

force protection.

w Develop all-source intelligence and counterintelligence required.

w Plan and coordinate civil affairs, civic action matters,

and military-diplomatic operations.

w Plan, conduct, and maintain communications and

information systems operations with subordinate,

higher, adjacent, and joint or allied forces.

w Provide the nucleus of the Arrival Assembly Operations Group for MPF operations

w Coordinate the submission of requirements for the

receipt and distribution of material resources for

logistic support of assigned forces.

w Function as a joint force land, air, or maritime

component headquarters when designated and when

provided with appropriate augmentation from the

supported unified commander and the other service

components.

c. Organization

The MEF CE consists of—

w Command Section.

w G-1 Division (personnel and administration).

w G-2 Division (intelligence and counterintelli-gence).

w G-3 Division (operations and training).

w G-4 Division (logistics).

w G-5 Division (plans).

w G-6 Division (communications and information 

systems).

w Comptroller Division.

w Communication Security Management Office.

w Special Operations Training Group.

w Staff Judge Advocate Branch.

Chapter 6

MAGTF Command Elements and Supporting Units
w Public Affairs Office Branch.

See figure 6-1.

The MEF CE maintains the ability to deploy a forward

warfighting CE, MEF (FWD), capable of exercising operational control of assigned and/or attached forces. The MEF

(FWD) will function either as the precursor for the deployment of the entire MEF, or conduct operations of limited

scope or duration, when deployment of the entire MEF is

not necessary.

d. Concept of Employment

The size and concept of employment of a deployed MEF

can vary greatly depending on the requirements of the

mission. A MEF can deploy and employ not only its own

units, but also units from other standing MEFs, the Marine

Corps Reserve, or other Services. The MEF Command

Element is capable of independent employment, but may be

satellited on the headquarters of one of its major subordinate

commands. It is capable of up to Corps-sized missions

across the range of military operations, including amphibious

assault and sustained operations ashore in any environment.

In doing so, the MEF CE is capable of executing command

and control of four to five Marine/joint/combined maneuver

divisions along with other major subordinate aviation,

combat service support, and other commands. Normally,

there is no requirement for a subordinate Marine Air-Ground

Task Force CE. However, forces employed in widely

separated areas may require a subordinate MAGTF CE.

e. Support Capabilities

(1) Communications and Information

Systems (CIS)

(a) The G-6, Communications and Information Systems

Officer, is responsible for the formulation of CIS plans and

policies for the MEF.

(b) The MEF CE has sufficient CIS resources to satisfy

internal requirements. Its communications detachment is

responsible for the installation, operation, and maintenance of

single and multi-channel channel radio, tactical telephone,

and satellite systems. Access will typically be required to

pertinent MAGTF local area networks (LANs) and wide

area networks (WANs). Additionally, joint world wide intelligence communications system (JWICS), secret internet

protocol router network (SIPRNET), and non-classified

internet protocol router network (NIPERNET) will be

required for all operations.

organic communications to satisfy its internal voice communications circuits requirements. 

The MHG and its subordinate elements have sufficient information systems resources to satisfy internal requirements.

Access will typically be required to pertinent MAGTF

LANs and WANs. Secret Internet Protocol Router

Network (SIPRNET) and Joint Worldwide Intelligence

Communications System (JWICS) access will generally be

required either for the MHG/detachment or subordinate

elements.

(2) Firepower. Organic firepower capability is limited to

individual and crew-served weapons.

(3) Administrative. The MHG is capable of selfadministration. Detachments operating in support of smaller

MAGTFs, however, are not usually capable of selfadministration; administrative support must be provided by

the supported unit.

(4) Maintenance.The MHG is authorized and capable

of performing 1st and 2d echelon maintenance of all organic

equipment. (See paragraphs 6006 and 6010 for more information on their unique maintenance capabilities.)

(5) Supply. The MHG is capable of performing organic

provided by the supported unit.

(6) Transportation. The MHG and its detachments

have organic vehicular transportation. Both will depend on

the supported unit or other external assets for transportation

of the entire unit in one echelon.

(7) Medical. The MHG is capable of providing routine

and emergency treatment and preparation for evacuation by

using its organic medical section. Medical support for MHG

detachments must be provided by the supported unit.

(8) Messing. The MHG is capable of providing organic

food service support. Food service support of MHG

detachments is provided by the supported unit.

6005. Radio Battalion

a. Mission

The mission of the radio battalion is to provide tactical signals

intelligence (SIGINT), ground-based electronic attack (EA),

communications security (COMSEC) monitoring, and

special intelligence (SI) communication support to the

MAGTF.

b. Tasks

w Conduct tactical (SIGINT) support operations in

support of any MAGTF operation, includ- ing

intercept, radio direction finding (DF), recording,

and analysis of communications and noncommunications signals, and SIGINT pro- cessing, analysis,

production, and reporting.

w Conduct EA against enemy or other hostile

communications.

w Conduct COMSEC monitoring and reporting on

friendly force communications.

w Provide SI communications support and cryptographic guard (personnel and terminal equipment) in

support of MAGTF CEs and battalion operations.

(Note: communications connectivity for SI communications is provided by the communications unit

supporting the MAGTF CE.)

w Provide SIGINT support units (SSUs) to MAGTFs

that are task organized with designated SIGINT,

EA, sensitive compartmented information (SCI)

communications, and other capabilities.

w Provide radio reconnaissance teams with specialized insertion and extraction capabilities (combat

rubber raiding craft, fast rope, rappel, helocast,

6-6 MCRP 5-12D
static line parachute) to provide specified SIGINT

and EA support during advance force, preassault,

or deep postassualt opera- tions.

c. Organization

There are two radio battalions within the operating force: 1st

Radio Battalion, which is under the OPCON of

COMMARFORPAC and is responsible for providing

support to it and I and III MEF; and 2d Radio Battalion,

which is responsible for support to MARFORLANT and II

MEF. 1st Radio Battalion consists of an H&S company and

three operational companies (T/O numbers 4737D and

4735D); 2d Radio Battalion consists of an H&S company

and two operational companies (T/O numbers 4737M and

4735M). The operational companies of the radio battalion

are not tactical organizations, but instead serve as training and

administrative units from which personnel and equipment are

drawn to form task-organized SSUs. A radio battalion SSU

will be task organized around all or most of the following

elements: a headquarters element, an operations control and

analysis center or collections/DF element, an EA element, an

SI communications element, a service support element, and

a radio reconnaissance element. See figure 6-4.

d. Concept of Employment

During operations the radio battalion or its task-organized

SSUs are under OPCON of the MAGTF commander,

who exercises this control through the G-2/S-2. Radio

battalions/SSUs are employed in either general support or

direct support. Under general support, battalion/SSU

elements are tasked by the MAGTF commander through

his G-2/S-21 to satisfy specified requirements of the entire

force. Alternatively, SSUs may be placed in direct support

of a subordinate commander to provide focused

SIGINT/EA for particular phases of an operation. Finally,

when MAGTFs of less than a full MEF size are deployed, a

SSU will normally be attached to the MAGTF CE (e.g.,

with a MEU(SOC)).

An entire radio battalion will support a MEF. MAGTFs of

smaller size will generally be supported by a task-organized

SSU. The radio battalion headquarters/SSU headquarters

and its S-3/operations control and analysis center sections

will normally locate in the vicinity of the MAGTF CE main

command echelon/combat intelligence center to facilitate

operational planning, command and control, and support.

SIGINT support teams from the battalion’s operational

companies will be task organized in a manner that is consistent with the MAGTF’s and subordinate units’ missions, the

Organization of Marine Corps Forces 6-7

1 The principal mission of the radio battalion/SSU is to support MAGTF intelligence operations. Accordingly, the G-2/S-2 has the

preponderance of staff responsibility for radio battalion/SSU operations. However, EA and COMSEC monitoring taskings are

operations responsibilities and thus will be the responsibility of the MAGTF G-3/S-3. Close coordination between the G-2/S-2

and G-3/S-3 is necessary to ensure effective, coordinated radio battalion/SSU operations.

c. Organization

Each MEF has an organic intelligence company.3The intelligence company consists of a headquarters section, a

topographic platoon, a SCAMP, an FIIU, and two direct

support teams. (See figure 6-5.)

d. Concept of Employment

The intelligence company is under OPCON of the MEF

commander, who exercises this control through the G-2.

During operations, intelligence company units are employed

in either general support or direct support. Under general

support, intelligence company elements are tasked by the

MAGTF commander through the G-2/S-2 to satisfy the

requirements of the entire force. Alternatively, task-organized

detachments consisting of elements from some or all of the

intelligence company’s subordinate units may be placed in

direct support of a subordinate commander to focus intelligence support for particular phases of an operation or to

create enhanced intelligence nodes in support of subordinate

elements. Finally, when MAGTFs of less than a full MEF

Organization of Marine Corps Forces 6-11

3 Within I MEF, 1st Intelligence Company is administratively subordinate to MEF headquarters group. Within II MEF, 2d Intelli

gence Company is subordinate to 2d Radio Battalion. Within III MEF, 3d Intelligence Company is subordinate to Headquarters

Battalion. The organization of Marine Corps intelligence and reconnaissance units is undergoing review and is subject to

change. Accordingly, the organization, manpower numbers, equipment, and quantities for intelligence and reconnaissance

units presented in this chapter may vary significantly within units. Refer to the following T/O numbers for current information:

Intelligence Company, 4707D; Topographic Platoon, 1st and 2d Intelligence Company 4708; 3d Topographic Platoon, 4708H;

size are deployed, task-organized detachments from intelligence company will normally be attached to the MAGTF

CE.

The intelligence company, task-organized detachments, or its

subordinate units’ concepts of employment are situationally

dependent. The following paragraphs provide basic employment planning guidance.

(1) Topographic Platoon. This platoon is capable of

supporting simultaneously three MEUs/SPMAGTFs in

addition to a MEF. This capability will generally be as

follows.

w MEU or a SPMAGTF—Support will be provided

by a terrain analysis team.

w MEF—Support will be provided by the entire

topographic platoon.

(2) SCAMP. When operating in support of the MEF,

the SCAMP will generally be employed as a platoon.

SCAMP employment in support of MEF subordinate units

or MAGTFs smaller than a MEF will generally be task

organized around either a sensor employment squad or a

sensor employment team. A MEU (SOC) typically has no

organic SCAMP element; instead, the parent MEF

maintains a CONUS-based sensor employment team ready

to deploy on 24-hours notice if a MEU (SOC) requires

support.

(3) FIIU. This unit is capable of supporting one MEF.

Support to MEUs or other smaller MAGTFs will generally

be provided by an imagery analysis detachment.

(4) Direct Support Team. Primary employment of

direct support teams is as organic teams either attached to or

placed in direct support of a designated subordinate

commander (e.g., the MEF main effort, a MEU, or an

SPMAGTF). Additionally, when not so employed the

direct support teams will generally augment the MAGTF

AFC.

e. Administrative, Logistic, and Other

Support Capabilities

(1) Administrative. The intelligence company and its

subordinate units are not capable of self-administration.

Administrative support is provided by the MEF unit to which

it is ADCON or other designated unit. Administrative

support for intelligence company detachments is provided by

the supported unit.

(2) Communications and Information Systems.

The intelligence company and its subordinate elements have

sufficient communications resources to support internal

company/detachment command and control, operations,

and intelligence requirements. Intelligence company subordinate units’ communications capabilities generally consist of

short- and medium-range voice communications equipment.

There are, however, no communications personnel organic

to the intelligence company. Communications requirements

beyond these must be provided by the supported unit.

All elements have sufficient information systems resources to

satisfy internal needs. Each will generally require access to

pertinent LANs and designated WANs. The topographic

platoon and the direct support teams will typically require

access to the SIPRNET; the FIIU likewise typically requires

access to the SIPRNET as well as to the JWICS. The

direct support teams also may require JWICS access.

(3) Firepower.Organic firepower capability is limited to

individual and crew-served weapons.

(4) Maintenance.The intelligence company and its

subordinate units are capable of 1st echelon maintenance of

organic equipment. With the following exceptions, all higher

maintenance is provided by the MEF unit to which it is

ADCONCSSEs, or the supported unit.

(a) SCAMP. The SCAMP is capable of 1st through 4th

echelon maintenance on all organic remote sensor equipment. It is the only designated intermediate maintenance

activity for tactical remote sensor equipment; therefore,

evacuation via the CSSE intermediate maintenance activity is

not required.

6-12 MCRP 5-12D
(b) FIIU.The FIIU is capable of 1st through 4th echelon

maintenance of organic imagery equipment.

(5) Supply. Supply support is provided by the MEF unit

to which it is ADCON;CSSEs; or the supported unit.

(6) Transportation. The intelligence company has

limited organic vehicular transportation support to support

the company and subordinate units’ operations. External

transportation support from the MEF unit to which it is

ADCON,CSSEs, or the supported unit is necessary to

displace all company elements.

(7) Medical.Medical support is provided by the MEF

unit to which it is ADCON,CSSEs, or the supported unit.

(8) Messing. Messing support is provided by the MEF

unit to which it is ADCON,CSSEs, or the supported unit.

w Conduct specialized terrain reconnaissance, including reconnaissance of hydrography, beaches,

roads, bridges, routes, urban areas, helicopter

landing zones, airborne drop zones, landing craft air

cushion (LCAC) landing zones, and aircraft

forward operating sites.

w When properly organized with other forces, equipment, or personnel, conduct engineer, NBC,

mobile, and other unique reconnaissance missions.

w Implant and/or recover sensors and beacons.

w Conduct initial terminal guidance (ITG) for helicopters, landing craft, and parachutists.

w Engage selected targets with supporting arms or

organic weapons, as directed, including terminal

guidance of precision-guided munitions.

w Conduct post-strike reconnaissance to determine

and report battle damage to a specific target or

area.

w Conduct limited-scale raids. These operations

include, but are not limited to, seizing, damaging, or

destroying critical enemy targets; performing static

maritime platform and maritime interdiction operations; capturing selected enemy personnel; and

recovering sensitive items or personnel.

c. Organization

Each MEF has one organic force reconnaissance company: 

1st Force Reconnaissance Company with I MEF, 2d Force

Reconnaissance Company with II MEF, and 5th Force

Reconnaissance Company with III MEF. 8 The company

consists of a headquarters platoon, a supply and services

platoon, and five reconnaissance platoons. (5th Force

Reconnaissance Company has three reconnaissance

platoons.) Each reconnaissance platoon consists of 3 teams

containing 4 men each, for a total of 15 teams per company,

except for 5th Force Reconnaissance Company, which has

9 teams. See figure 6-8.

d. Concept of Employment

(1) The force reconnaissance company normally operates

under the staff cognizance of the MAGTFG-2/S-2 for

reconnaissance and surveillance missions and under the staff

cognizance of the MAGTFG-3/S-3 for offensive missions.

The basic operating unit is the team. However, platoons or

task-organized elements may be employed to accomplished

certain tasks.

(2) Force reconnaissance operations should have a

defined scope and duration, with planned exfiltration. Teams

are usually inserted into the supported commander’s area of

interest (usually the deep area), often well beyond the

supporting arms and reserve elements of the enemy’s

committed forces, to collect and report information in

response to the commander’s PIRs.

(3) When required by the situation, the company or

detachments may be placed in direct support of or attached

to smaller MAGTFs or to MEF elements other than the CE.

Normally a force reconnaissance detachment is attached to

a MEU(SOC).

7 The T/E number for the MCISU is N4010.

8 The organization of Marine Corps intelligence and reconnaissance units is undergoing review and is subject to change. Accord

ingly, the organization, manpower numbers, equipment and equipment quantities for intelligence and reconnaissance units

shown in this chapter may vary significantly within units. Refer to the following T/O numbers for current information: 1st and 2d

Force Reconnaissance Companies, 4718D, and 5th Force Reconnaissance Company, 4719C.
(4) Because force reconnaissance company units routinely

operate beyond the range of the MAGTF’s supporting

arms, the company must maintain the capability to clandestinely insert and extract units over extended distances. Such

means include foot movement, surface or subsurface

swimming, vehicles, rotary- or fixed-wing aircraft, small

boats, landing craft, and commercial assets. All teams are

capable of using closed-circuit underwater breathing apparatus, open-circuit SCUBA, and submarine lock-out. All

teams also are capable of static-line and military free-fall

parachuting.

(5) Deployed teams use standard techniques of small-unit

scouting and individual movement. Unless the mission

requires otherwise, force reconnaissance teams will avoid

contact with the enemy or indigenous people. Teams either

observe from vantage points or physically reconnoiter the

areas of interest. As directed, teams report by radio and/or

during postmission debriefings.

(6) When conducting offensive operations, force reconnaissance company elements employ the techniques

described above to reach their objective sites. Conducting

actions at the objective area, they employ close-quarter

battle, standard tactical assault, or sniper techniques to

neutralize or destroy enemy targets and/or to recover designated personnel or materiel.

(7) Teams assigned to ITG missions reconnoiter the

landing area and provide last-minute visual or electronic

terminal guidance to flight, wave, or stick leaders. ITG

missions terminate with the arrival of the helicopter support

team, U.S. Navy beach party, LCAC landing zone control

teams, U.S. Army Pathfinder teams, or U.S. Air Force

combat control teams, which then assume traffic-control

functions.

e. Administrative, Logistic, and Other

Support Capabilities

(1) Administrative. The force reconnaissance company

is capable of self-administration. Admini-strative support for

deployed platoons and detachments is provided by the

supported unit.

(2) Communications and Information Systems.

The force reconnaissance company and its subordinate

elements have sufficient communications resources to

support internal company/detachment command and

control, operations, and intelligence requirements. Communications capabilities generally consist of short-, medium-, and

long-range range voice communications equipment. 

The headquarters of the force reconnaissance company or

its detachments have sufficient information systems resources

to satisfy internal needs. They will generally require access to

pertinent LANs and WANs to support mission planning and

coordination.

(3) Firepower.Organic firepower capability is limited to

individual weapons.

(4) Maintenance. The force reconnaissance com- pany

and its subordinate units are capable of 1st and 2d echelon

maintenance support of organic equipment. Additionally,

(5) Supply. Supply support is provided by ttheMEF unit

to which it is ADCON,CSSEs, or the supported unit.

(6) Transportation. The force reconnaissance

company has limited organic vehicular transportation support

to support company and subordinate unit operations. External transportation support from the MEF unit to which it is

ADCON,CSSEs, or the supported unit is necessary to

displace all company elements.

(7) Medical. The force reconnaissance company is

capable of routine, emergency, and advance trauma treatment. Additionally, it can provide specially trained Navy

corpsmen in support of its detachments.

(8) Messing.Messing support is provided by the MEF

unit to which it is ADCON, CSSEs, or the supported unit.

headquarters company, a general support company, one or

three direct support companies,10 and a service company.11

See figure 6-9.

d. Concept of Employment

During operations the communication battalion or its taskorganized detachments are OPCON to the MAGTF

commander, who exercises this control through the

G-6/S-6. Elements of the battalion are organized to provide

specified general or direct support of the MARFOR

component commander or MAGTF CE. The MAGTF CE

G-6/S-6 exercises staff cognizance over MAGTF communications; to facilitate system planning and engineering, the

battalion conducts concurrent planning with the MAGTF

G-6/S-6.

Elements of the communication battalion may be employed

separately as task-organized detachments to support organizations smaller than a MEF CE, or the entire battalion may

be employed to support larger MAGTF CEs. The commun

ic

a

ti

o

n battalion will normally deploy as a task-organized unit or

will deploy task-or- ganized detachments in support of

MARFOR headquarters and MAGTF CEs. In support of

a MEF CE, the battalion in total will task organize to support

the deployment. Upon notification, and before deployment

of a smaller MAGTF CE or a MARFOR headquarters, a

direct support communications company will be taskorganized to support the deployment. The headquarters

company includes the structure necessary to provide detachments to support three MEUCEs.

e. Administrative, Logistic, and Other

Support Capabilities

(1) Communications and Information Systems.

The battalion and its detachments are fully capable of

supporting internal operations with organic communications

6011. Civil Affairs Group (CAG)

a. Mission

The CAG provides special staff support to the MEF during

the planning, assault and consolidation phases of landing

operations in naval campaigns, and may be utilized across

the operational spectrum. It plans, advises, coordinates,

conducts, supervises, and evaluates activities between

military and civilian forces in order to minimize mission interference, and to maximize civilian support for landing force

operations. These activities include interaction between the

MEF and inhabitants; Host Nation civil, police, and military

authorities; US. Non-military agencies; and a wide array of 

nongovernmental organizations (NGO’s). The CAG

supports the MEF’s careful attention to local culture,

customs, and traditions, in order to facilitate military operations and reduce friction.

b. Tasks

w Assist in planning and conducting landing force

operations.

w Assist in planning and conducting Civil Affairs (CA)

activities, to include Civil-Military Operations

(CMO).

w Control subordinate CA units when assigned.

w Plan and conduct survey, liaison and reconnaissance

efforts to initiate and conduct CA acti-vities.

w Coordinate with appropriate staff officers at higher,

adjacent, and lower commands.

w Coordinate with non-MAGTF organizations and

authorities.

c. Organization

A CAG is normally organized into a Group Headquarters

and three Civil Affairs Detachments. The commanding

officer and Group Headquarters provide CA support to the

MEF, while the detachments are designed to support units of

Organization of Marine Corps Forces 6-23
the MEF to include the MEF(FWD). Each detachment is

further organized into International Law, Public Health, and

Displaced Per- sons/Refugee functional teams, in addition to

three CA Teams, which can be placed in support of

MEU-sized elements. There are no active duty CAGs in

the U.S. Marine Corps; however, there are two CAGs

assigned to MARFORRES. The 3d CAG is located

aboard Camp Pendleton, California and is under the operational control of MARFORPAC. The 4th CAG is located

aboard Naval Station Anacostia in Washington, D.C. and is

under the operational control of MARFORLANT. Both

12Equipment and quantities shown are drawn from the T/E for 8th Communications Battalion, II MEF, as of 22 October 1997.

Refer to the following T/E for current information: 7th Communications Battalion, N4887; 8th Communications Battalion, N4787;

and 9th Communications Battalion, N4687. The quantities indicated are planned for the fiscal year shown. Numbers in this

column are additional items planned for the fiscal year indicated.
CAGs provide support to active duty headquarters--both in

real-world operations and exer- cises--on a constant basis

through a variety of means and funding sources. The majority of billets in the CAG are for MOS 0107, CA Officer or

8441, CA NCO. These are secondary MOSs so

members bring a wide variety of Primary MOSs, skills and

experience to the CAG. See figure 6-10. 

d. Concept of Employment

The CAG is organized to conduct CA activities in support of

the MAGTF mission and may include Civil-Military Operations. Normally, these activities do not include sustained

military or nation building/rebuilding operations. Whenever

the MAGTF operates in an inhabited area, civilian populations will impact operations. CA elements and personnel are

Economy of Force measures, intended to apply a few

Marines with special perspective and training to the

MAGTF’s planning and execution of operations. The CA

staff element serves to promote civilian actions and attitudes

helpful to the MAGTF and to minimize actions and attitudes

harmful to the MAGTF. Typically, the assigned CA staff

prepare assessments, agreements, and annexes in accordance with

 the Joint Operations Planning and Execution System

(JOPES) which support the commander's plans and mission

accomplishment. CA acti- vities always support the

commander’s legal and moral responsibilities under international and US law. 

The MAGTF G/S-3 has primary staff cognizance over the

CA efforts at the CE. Subordinate units plan and execute

CA activities when useful or as directed, and may be

assigned their own supporting CA elements or personnel. At

the MEF level, the CA element may receive substantial

direction from the Joint Force Commander’s CA staff

element or Joint Civil-Military Operations Task Force if

organized. Coordination with all staff elements is important,

but special consideration should be made to coordinate with

Public Affairs and Psychological Operations staffs to support

a common Information Operations campaign. Once the

MAGTF is established ashore, CA forces may establish a

Civil-Military Operations Center (CMOC) which serves as

focal point of coordination between MAGTF and civilian

planners.

While the CAGs are capable of limited self-admini- stration,

they depend on the supported unit for logistic, information

systems, and communications support.
