The Marine Corps, within the Department of the Navy (DON), is organized as a conventional force in readiness to support national needs. Deploying for combat as combined arms Marine air-ground task forces (MAGTFs), the Marine Corps provides the President and Secretary of Defense (SecDef) with a responsive force that can conduct operations across the range of military operations. Recent events continue to highlight the Navy-Marine Corps team's key national security role. Marine Corps forces are able to be tailored through task organization and equipped to meet the combatant commander's (CCDR's) needs in the conduct of expeditionary operations. This task organization provides versatility, flexibility, expandability, rapid deployability, and sustainability for military operations.

## Organization, Chain Of Command, And Staff Functions Two Parallel Chains Of CommandService And OperationalExist Within The Department Of Defense (Dod). The Service Chain Begins With The President Of The United States, Through Secdef, Through The Secretary Of The Navy (Secnav) And The Commandant Of The Marine Corps (Cmc), And To Marine Corps Units Not Assigned To The Ccdrs. The Operational Chain Runs From The President, Through Secdef, And Directly To Commanders Of Combatant Commands For Missions And Forces Allocated To Their Commands. Marine Corps Component Commanders Provide Marine Corps Operating Forces To Commanders Of Combatant Commands And Other Operational Commanders As Directed. The Marine Corps Is Divided Into Three Categories: Headquarters, United States Marine Corps (Hqmc) And Supporting Activities, The Marine Corps Operating Forces, And The Supporting Establishment. Collectively, They Form The Marine Corps.

The individual commander's staff within the Marine Corps is organized under a basic structure. This construct allows for units to mirror similar functions and create a unity of effort when performing duties laterally throughout the staff. General staffs are designated G-1 through G-10 while staffs of other commanders are designated S-1 through S-10. These like functions are grouped into staff areas:

- G-1/S-1 personnel. - G-2/S-2 intelligence. - G-3/S-3 operations and training. - G-4/S-4 logistics. - G-5/S-5 plans. - G-6/S-6 communications. - G-7/S-7 information environment. - G-8/S-8 finance/resource management. - G-9/S-9 civil affairs. - G-10/S-10 force preservation
The numbers assigned to a staff section are nominal in nature and do not indicate a hierarchy of importance. See figure 1-1 for a notional structure of the previously mentioned staff areas.

## Headquarters, United States Marine Corps

Headquarters, United States Marine Corps consists of the CMC, the Assistant Commandant of the Marine Corps (ACMC), deputy commandants (DCs), Staff Judge Advocate (SJA) to the CMC, directors, other members of the Navy and Marine Corps assigned or detailed to HQMC, and civilian employees in the DON assigned or detailed to HQMC. Headquarters, United States Marine Corps is located at the Pentagon; Henderson Hall; Marine Barracks Washington DC; Marine Corps Base (MCB) Quantico, Virginia; and the Washington Navy Yard. The HQMC structure is discussed in greater detail in chapter 15.

Under the authority, direction, and control of the SECNAV through the CMC, HQMC shall prepare for such employment of the Marine Corps and for such recruiting, organizing, supplying, equipping (including research and development), training, servicing, mobilizing, demobilizing, administering, and maintaining of the Marine Corps, and will assist in the execution of any power, duty, or function of the Secretary or the CMC. The function, composition, and general duties of HQMC are defined in Title 10, United States Code (USC), Subtitle C, Part I, Chapter 506, *Headquarters, Marine Corps*.

Most supporting activities report to the CMC or the ACMC; however, Marine Corps Systems Command (MARCORSYSCOM) reports directly to the assistant SECNAV, Research, Development, and Acquisition. Supporting activities include, but are not limited to, Marine Corps Combat Development Command (MCCDC), MARCORSYSCOM, Marine Corps Recruiting Command (MCRC), and MCOTEA [Marine Corps Operational Test and Evaluation Activity]. Marine Corps embassy security forces are under the control of the Secretary of State and provide security and services or perform other special duties for agencies other than the DON. Assignment of the missions of these forces and the personnel to them are specified by the supported agency and approved by the CMC. External Marine Corps support to other activities and agencies includes individual manpower provided to joint, DOD, US Navy, and other activities as required. Additionally, organizations, such as Marine Corps Embassy Security Group forces and Marine Cryptologic Support Battalion (MCSB) forces, are organized by the CMC for missions directed by the Secretary of State or the heads of the National Security Agency/ Central Security Service (NSA/CSS).

## Marine Corps Operating Forces

Marine Air-Ground Task Forces.The Marine Corps generally operates as MAGTFs, which are integrated, combined arms forces that include air, ground, and logistic units under a single commander. Marine air-ground task forces are organized, trained, and equipped from the operating forces of Marine Forces Pacific (MARFORPAC), Marine Forces Command (MARFORCOM), and Marine Forces Reserve (MARFORRES). Commander, MARFORPAC and Commander, MARFORCOM provide the geographic combatant commanders (GCCs) with scalable MAGTFs that possess the unique ability to project mobile, reinforceable, sustainable combat power across a range of military operations. Commander, MARFORRES provides ready and responsive Reserve Marine forces and Marines who augment and reinforce Active Component MAGTFs in their mission accomplishment. As depicted in figure 1-2, on page 1-4, a MAGTF consists of four key elements: a command element (CE), a ground combat element (GCE), an aviation combat element (ACE), and a logistics combat element (LCE).

Marine Expeditionary Force.The Marine expeditionary force (MEF) is the principal Marine Corps warfighting organization. It is capable of missions across a range of military operations, to include amphibious assault and sustained operations ashore in any environment. With appropriate augmentation, the MEF CE is capable of performing as a joint task force (JTF) headquarters. There are three standing MEFs: I MEF, based in southern California and Arizona; II MEF, based in Virginia, North Carolina, and South Carolina; and III MEF, based in Japan and Hawaii. Each standing MEF consists of a permanent CE, one Marine division (MARDIV), one Marine aircraft wing (MAW), and one Marine logistics group (MLG). These major commands constitute the primary reservoir of combat capabilities from which MAGTFs are sourced. See figure 1-3, on page 1-5, for a notional MEF structure.

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, other Services, and the United States Special Operations Command (USSOCOM). A MEF typically deploys by echelon with up to 60 days of sustainment. The lead echelon of the MEF, tailored to meet the specific mission, is designated the Marine expeditionary force (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. Marine expeditionary forces 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.

Marine Expeditionary Brigade. As a subordinate command of the MEF, the Marine expeditionary brigade (MEB) accomplishes such operational missions as may be assigned based on augmentation. The MEB is a mid-sized MAGTF that conducts major security cooperation operations, responds to larger crises or contingencies, or participates in major operations and campaigns. Each MEB orients toward its respective GCC's area of responsibility (AOR) and provides general officer-level crisis response JTF command. Marine expeditionary brigades provide the building blocks for forcible entry and other power projection operationsthe landing forces for amphibious assault and the fly-in echelons that marry-up with equipment and supplies delivered by maritime prepositioning ships. Marine expeditionary brigades accomplish such operational missions as may be assigned based on augmentation.

NOTE: 1 III MEF has only one MEU.

For more detail of respective division, unit, group, or wing, see respective organizational chart (e.g., Marine Logistics Group).

The MEB is a MAGTF built around a reinforced infantry regiment, an aircraft group, and components of an MLG. When designed by GCC as a JTF, the MEB can be augment by the US Army, US Air Force, or coalition forces, depending on the mission assigned. The MEB is normally commanded by a brigadier general. There are three regionally oriented MEBs: 1st MEB aligned to I MEF (United States Indo-Pacific Command [USINDOPACOM]/United States Central Command [USCENTCOM]), 2d MEB aligned to II MEF (United States European Command [USEUCOM], United States Africa Command [USAFRICOM], USCENTCOM), and 3d MEB aligned to III MEF (USINDOPACOM). A MEB can consist of 3,000 to 20,000 Marines and Sailors once its subordinate units are assigned and deploys with up to 30 days of sustainment. See figure 1-4 for a notional MEB structure.

Command Element. The MEB CE is responsible for the command and control (C2), direction, planning, and coordination of air, ground, and logistic operations as well as operations in the information NOTE: 1 2d and 3d MEBs have a standing CE, with allocated permanent structure, that may require augmentation upon activation.

1st MEB is a battle-rostered organization only.

environment (OIE). Additionally, the MEB CE is responsible for gaining and maintaining joint headquarters certification. The MEB CE is manned and equipped to form the nucleus of a MAGTF or JTF headquarters. The MEB CE can exercise command and control of a MAGTF or JTF from the sea or ashore, and may require augmentation to affect the command and control of larger contingency operations. The MEB CE consists of a commanding general (CG) and a staff necessary to provide command and control of assigned forces. As with all other MAGTF elements, the MEB CE can be task-organized and augmented and/or assigned additional C2 and intelligence capabilities from national and theater assets, force reconnaissance assets, signals intelligence (SIGINT) capabilities, and/or a force fires coordination center. Additionally, a MEB CE can employ additional major subordinate commands (MSCs), such as the force artillery headquarters, naval construction regiments, and/or US Army maneuver or engineering units. Each MEB CE orients on the respective GCC's AOR and provides a general officer-level crisis response headquarters that may require augmentation for the command and control of larger contingency operations. The MEB CE provides a transitional capability between the forward-deployed Marine expeditionary unit (MEU) and the MEF. The MEB CE deploys to CCDR AOR for employment as part of a joint, combined, or multinational force and is responsible for conducting sustained combat operations and projecting offensive power ashore.

Ground Combat Element. The GCE is composed of an infantry regiment reinforced with artillery, reconnaissance, engineer, light armored reconnaissance (LAR) units, assault amphibian units, and other attachments as required.

Aviation Combat Element. The ACE is composed of combat assault transport helicopter/tiltrotor aircraft, utility and attack helicopters, fixed-wing (FW) attack vertical and/or short takeoff and landing aircraft (V/STOL), fighter/attack aircraft, unmanned aircraft systems (UASs), air refueler/transport aircraft, and requisite aviation logistic and command, control, computers, communications, and intelligence capabilities.

Logistics Combat Element. The LCE is task-organized around components of an MLG consisting of the MLG
headquarters and two combat logistics regiments (CLRs). These components support the following logistic functions: engineering, supply, services, transportation, medical/dental, and maintenance, as well as, landing support for beach, port, and airfield delivery operations. In garrison, all routine operational support for the MEB CE is provided by Marine expeditionary force support battalion (MSB). However, during training and contingency operations any logistic support that is required beyond MSB capability will be provided by the LCE of the MEB. Each MEB consists of a standing MEB CE that serves as the nucleus of a MAGTF headquarters or JTF. The MEB does not have assigned forces, but will establish habitual relationships with the associated major subordinate elements (MSEs) through planning and exercises. Subordinate elements are primarily drawn from the MEF to which the MEB is assigned when forces are required. Initial crisis response planning and execution are conducted by the core MEB CE staff, with augmentation provided to the core staff and forces assigned as deemed necessary for the given mission. If designated as a JTF, the MEB augmentation can consist of Marines, Soldiers, Sailors, Airmen, and/or coalition forces as outlined by the designated CCDR. As an expeditionary force, a MEB is capable of rapid deployment and employment via amphibious shipping, strategic airlift, marrying with maritime prepositioning force (MPF) assets, or any combination thereof. If the scope of operations expands beyond the capability of the MEB, additional forces can readily deploy to expand to a MEF. Thus, the MEB becomes the forward echelon of the MEF. Additionally, the MEB bridges any potential gap that exists regarding crisis response. It exercises command and control over Marine Corps forces, while enabling a general officer-level command and control of crisis response operations when requested by the GCC through the Marine Corps component commander.

Marine Expeditionary Unit. The MEU is the standard forward-deployed Marine expeditionary organization
(see fig. 1-5). Forward-deployed MEUs are maintained by MARFORCOM and MARFORPAC in the Mediterranean Sea, the western Pacific, and the Indian Ocean or Arabian Gulf region. The MEU can be thought of as a self-contained operating force capable of missions of limited scope and duration and as a forward-deployed extension of the MEF or MEB. The MEU undergoes an intensive 26-week, standardized predeployment training program that includes an exercise and a final evaluation in order to receive its certification as a MEU. The MEU must demonstrate competence across the entire range of required capabilities, be able to plan and execute any assigned mission within 6 hours of notification, and conduct multiple missions simultaneously. Marine expeditionary units are augmented with selected personnel and equipment to provide enhanced conventional and selected maritime special operations capabilities.

There are seven MEUs: the 11th, 13th, and 15th MEUs reside in I MEF; the 22d, 24th, and 26th MEUs reside in II MEF; and the 31st MEU resides in III MEF. Each MEU is task-organized with up to15 days sustainment and consists of

- A standing CE.
- A GCE consisting of an infantry battalion reinforced with artillery, reconnaissance, engineer, armor,
assault amphibian units, and other detachments as required. This reinforced infantry battalion forms a battalion landing team (BLT).
- An ACE consisting of a Marine medium tiltrotor squadron (VMM) reinforced with detachments
from a Marine heavy helicopter squadron (HMH), Marine light attack helicopter squadron (HMLA), Marine attack squadron (VMA), Marine unmanned aerial vehicle squadron (VMU), Marine air traffic control detachment (MATCD), Marine wing support squadron (MWSS), and Marine aviation logistics squadron (MALS).
- An LCE consisting of a combat logistics battalion (CLB).
The MEU's mission is to provide the President and/or SecDef and the CCDRs with a forward-deployed, seabased, 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 a range of military operations in support of various contingency requirements, including such selected maritime special operations as reconnaissance and surveillance; tactical recovery of aircraft and personnel; seizure/recovery of selected personnel or materiel; and visit, board, search, and seizure of vessels. Embarked aboard the ships of a Navy amphibious ready group, a deployed MEU provides a CCDR or other operational commander with a quick, sea-based reaction force for a wide variety of situations. In many cases, the MEU embarked on amphibious warfare ships may be the first US 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 willingness of the United States to protect its interests overseas.

Special Purpose Marine Air-Ground Task Force. Each standing special purpose Marine air-ground task force (SPMAGTF) CE will serve as the nucleus of a SPMAGTF, which is a MAGTF formed to conduct a specific mission. It is normally formed when a standing MAGTF or other type force is either inappropriate or unavailable. A SPMAGTF is organized, trained, and equipped to conduct a wide variety of missions that include crisis response, regionally-focused training exercises, and peacetime missions. The SPMAGTF designation derives from the mission it is assigned, the location in which it will operate, or the name of the exercise in which it will participate (e.g., SPMAGTF (X), SPMAGTF Somalia, SPMAGTF UNITAS, SPMAGTF Andrew). A SPMAGTF may be any size, but is normally smaller than a MEU with tailored capabilities chosen to accomplish a particular mission. It may be task-organized deliberately from the assets of a standing MEF, or it may be formed on a contingency basis from an already deployed MAGTF to perform an independent, rapid response mission of limited scope and duration. The SPMAGTF includes all four of the basic elements of a MAGTF. It is generally employed in the same manner as a MEU; however, under certain circumstances it may be deployed via commercial shipping or aircraft, intertheater airlift, or organic Marine aviation.

## 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 approximately 30,000 Marines. Additionally, the supporting establishment includes those civilian activities and agencies that provide support to Marine Corps operating forces. In keeping with the Marine Corps' expeditionary nature, these installations that support the MEFs are strategically located near aerial ports and seaports of embarkation and are serviced by major truck routes and railheads to allow for the rapid and efficient movement of Marines and equipment.

## Marine Corps Components

The President establishes unified combatant commands to execute broad and continuing missions at the strategic level using forces of two or more Military Departments. Combatant commands typically have geographic (e.g., USCENTCOM) or functional (e.g., United States Transportation Command) responsibilities. The CCDR exercises combatant command (command authority) over assigned forces. A CCDR may establish a subordinate unified command. A subordinate unified command contains forces from two or more Military Departments and conducts operations of a smaller scope or more limited duration that do not require all of the forces assigned or attached to the combatant command. The establishing authority for subordinate unified commands dissolves when the mission is complete or when it is no longer required. Marine Corps operating forces are generally assigned to combatant commands by the SECNAV through the annual SecDef Memorandum, *Forces for Unified Commands,* published in the Global Force Management Implementation Guidance. With the disestablishment of United States' Joint Forces Command, some operational forces are Service retained, such as MARFORCOM. The CCDRs coordinate with their Service component commanders to organize forces to accomplish their assigned mission. The Marine Corps component commander functions at the operational level of war and is responsible to accomplish the assigned mission, provide forces, and accomplish operational-level administrative and logistic tasks to assigned or attached Marine Corps forces. Component commands normally exercise operational control (OPCON) of forces assigned or attached to their CCDR or they may be limited to tactical control of these forces. Since the individual Services are organized, trained, equipped, and employed using each Service's doctrine, this arrangement fully exploits the capabilities and experience the individual Services can bring to a joint command. Exercising OPCON of Marine Corps forces allows the Marine Corps component commander to take full advantage of the Marines' established lines of command and standing operating procedures. It enables Marine Corps forces to function as they were designedas a MAGTF.

## Marine Forces Reserve

The MARFORRES, composed of the Reserve Component of the Marine Corps total force, has a mission to augment and reinforce the Active Component with trained units and qualified individuals in a time of war, national emergency, or contingency operations; provide personnel and operational tempo relief for the active forces in peacetime; and provide service to the community. The Marine Corps Reserve Component complements Active Component force structure and capabilities. Charged with providing the means for rapid expansion of the Marine Corps during national emergency, the Marine Corps Reserve Component provides the added capability, flexibility, and depth that are the foundation for sustainment at any level of recall or mobilization. Total force integration is the dominant theme for all Reserve planning, training, and administration. The Marine Corps Reserve Component is made up of the Ready Reserve, the Standby Reserve, and the Retired Reserve.

## Ready Reserve

The Ready Reserve consists of Reserve units and individual members who are liable for immediate active duty during war or national emergency. The Ready Reserve includes the Selected Reserve and the Individual Ready Reserve (IRR).

Selected Reserve. The Selected Reserve is that part of the Ready Reserve consisting of members of Selected Marine Corps Reserve units, individual mobilization augmentees, and members serving on the Active Reserve program. Selected Marine Corps Reserve units include subordinate units within the 4th MARDIV, 4th MAW, 4th MLG, and Force Headquarters Group (FHG) of MARFORRES. All Selected Marine Corps Reserve units are under the administrative control (ADCON) and OPCON of Commander, MARFORRES. Individual mobilization augmentees are individuals from the Selected Reserve who receive training and are preassigned to an Active Component organization billet. Such a billet must be filled to meet the requirements of the organization to support mobilization (including pre- and/or post-mobilization) requirements across a range of military operations and training. Reservists on active duty with the Active Reserve program serve in full-time active duty billets that support the organization, administration, recruiting, retention, instruction, and training of the Marine Corps Reserve Component.

Individual Ready Reserve. The IRR is a CMC manpower pool principally consisting of individuals who are available for mobilization, have had training, have previously served in the Active Component or in the Selected Reserve, and who are in one of the following categories:

- Have not completed their military service obligation. - Have completed their military service obligation and are in the Ready Reserve by voluntary agreement.
- Have not completed their military service obligation and are mandatory participants, but are authorized
to transfer to the IRR.
Upon completion of their military service obligation, reserve officers will continue to serve in the IRR contingent on minimum participation requirements and statutory limitations, unless transfer or resignation is requested sooner. The Marine Corps Individual Reserve Support Activity provides administrative services to all IRR Marines.

## Standby Reserve

The Standby Reserve consists of Marines who are unable to meet participation requirements of the Ready Reserve and desire to maintain their affiliation, are bound by contractual obligation, or are officers who have failed to resign their commission. The Standby Reserve is comprised of two categories: Standby Reserve-Active Status List and Standby Reserve-Inactive Status list. These individuals are not required to train and are not members of units; however, they may be mobilized as needed to fill manpower requirements for specific skills.

## Retired Reserve

The Retired Reserve consists of Marines who have requested and have been approved for retirement. Members of this category may be recalled to active duty under Title 10, USC, Subtitle A, Part II, Chapter 39, Section 688, Retired Members: authority to order to active duty; duties.

## Chapter 3 Marine Air-Ground Task Force Command Elements Marine Expeditionary Force Command Element

The mission of the MEF CE is to deploy and be employed by a CCDR as a standalone CE or, with appropriate augmentation, as the core element of a JTF headquarters in support of a joint, combined, or multinational contingency response in order to

- Command and control three or more organic MSCs and other attached units during amphibious or
expeditionary operations and exercises.
- Direct, plan, and coordinate Marine Corps-level air, ground, and logistical operations as well as OIE of
assigned forces, normally consisting of one or more MARDIV, MAW, MLG, and other separate units.
- Plan and direct the employment of firepower with MEF CE assigned forces across its assigned area of
operations (AO), project offensive power ashore, and conduct sustained combat operations.
- Prepare and deploy combat ready MAGTFs to support CCDR contingency response or war, conduct
presence and crisis response, and support Service and CCDR initiatives, as required.
- Augment the supporting establishment with air, ground, logistic, and information forces to operate
garrison infrastructure necessary to ensure operating forces are organized, trained, equipped, and ready for prompt and effective employment in any climate or terrain.
There are three MEF CEs: I MEF CE located at Camp Pendleton, California; II MEF CE located at Camp Lejeune, North Carolina; and III MEF CE, located at Camp Courtney, Okinawa, Japan. The MEF CE consists of a commanding general and the staff necessary to provide command and control of assigned forces. A MEF CE can be task-organized and augmented and/or assigned additional C2 and intelligence capabilities from national and theater assets, force reconnaissance assets, and/or a force fires coordination center. Additionally, a MEF CE can employ additional MSCs, such as the force artillery headquarters, naval construction regiments, and/or US Army maneuver or engineering units. A notional MEF CE structure is displayed in figure 1-3 on page 1-5. The MEF, as the largest MAGTF construct, is task-organized around a permanent MEF CE and is manned and equipped to form the nucleus of a JTF or MAGTF headquarters, with exception of II MEF CE. The size and composition of a deployed MEF can vary greatly depending on mission requirements, but the CE (with augmentation) is capable of conducting corps-sized operations across a range of military operations (command and control of four to five Marine, joint, or multinational maneuver divisions along with other major subordinate aviation and combat logistics elements and other commands). It can deploy not only with its own MSCs, but also with units from the other standing MEFs, the Marine Corps Reserves, other Services and commands, and, during multinational operations, with foreign forces assigned or attached.

The MEF CE can exercise command and control of a JTF from the sea or ashore and function as a JTF headquarters core CE, providing command and control over all seven major warfighting functions. The MEF typically deploys by echelon with up to 60 days of sustainment. The lead echelon of the MEF, tailored to meet the specific mission, is designated the MEF (FWD). The MEF commander may command the MEF (FWD) personally, or it may be commanded by a designated commander. The MEF (FWD) missions and duties may also be filled by one of the standing MEB CEs. During peacetime operations, the MEF CE performs regular staff functions; plans, trains, and prepares for scheduled deployment to various exercises; and maintains readiness for deployment in support of contingency response. During major combat operations, the MEF CE deploys and conducts command and control of attached forces under the direction of the CCDR or JTF commander.

## Marine Expeditionary Brigade Command Element

The mission of the MEB CE is to deploy and be employed by a MEF or GCC as a standalone CE and, with appropriate augmentation, as the core element of a JTF headquarters in support of a joint, combined, or multinational contingency response. Its functions are to

- Command and control three or more MSEs and assigned other Service and coalition units during
amphibious or expeditionary operations and exercises.
- Direct, plan, and coordinate Marine brigade-level air, ground, and logistical operations as well as OIE of
assigned forces, normally consisting of one or more Marine regiments, Marine aircraft groups (MAGs), CLR, brigade information group, and other separate units.
- Plan and direct the employment of firepower across its assigned AO. - Project offensive power ashore and conduct sustained combat operations.
There are two standing MEB CEs in the Marine Corps: 2d MEB CE, located at Camp Lejeune, North Carolina; 3d MEB CE, located at Camp Courtney, Okinawa, Japan. The 1st MEB CE is located at Camp Pendleton, California, but it is not a standing CE; rather, it is task-organized from within I MEF as the situation requires. Each standing MEB CE consists of a commanding general and a small staff that forms the nucleus of a MEB headquarters. The MEB CE can be task-organized and must be augmented with additional assets to provide the necessary capability to command and control a MEB. A notional MEB CE structure is displayed in figure 1-4 on page 1-6. The standing MEB CE serves as the nucleus of a JTF or MAGTF headquarters. Initial crisis response planning and execution will be conducted by this core MEB staff, with augmentation provided to the core staff and forces assigned as deemed necessary for the given mission. Each MEB CE establishes habitual relationships with the associated MSE within their assigned MEF through planning and exercises. Subordinate elements will be drawn primarily from the MEF to which the MEB CE is assigned, when required. During normal peacetime operations, the MEB CE performs regular staff functions; plans, trains, and prepares for scheduled deployment to various exercises; and maintains readiness for deployment in support of contingency response. The MEB CE bridges any potential gap that exists regarding crisis response and exercises command and control over Marine Corps forward-deployed forces, while providing the ability to exercise general officer-level command and control of crisis response operations when requested by the GCC through the Marine component commander. During major combat operations, the MEB CE deploys and conducts command and control of attached forces under the direction of the MEF CG or functional component.

## Marine Expeditionary Unit Command Element

The mission of the MEU CE is to provide command and control, direction, planning, and coordination of air, ground, and logistic operations of assigned forces, generally consisting of a BLT, a composite aviation squadron, a CLB, and other selective capabilities. The MEU is the standard, forward-deployed Marine expeditionary organization. The MEU CE consists of a commanding officer and staff necessary to provide the requisite capability to command and control a MEU. There are seven standing MEU CEs: the 11th, 13th, and 15th MEU CEs reside with I MEF; the 22d, 24th, and 26th MEU CEs reside with II MEF; and the 31st MEU CE resides with III MEF. The MEUs with I and II MEF operate on a rotational deployment cycle, with one MEU generally deployed, one working up for deployment, and the other in a deployment recovery state. The III MEF MEU employs on a more continuous cycle due to its forward-deployed nature. As a MEU is preparing to deploy, its maneuver elements and other attachments are composited from organizations throughout its MEF, generally consisting of the following:

- A BLT (infantry battalion reinforced with artillery, reconnaissance, engineer, armor, assault amphibian
units, and other detachments, as required).
- A reinforced rotary-wing (RW) squadron or reinforced tiltrotor squadron (transport, utility, and attack
helicopters).
- A detachment of FW attack V/STOLs, refuelers, and other detachments, as required. - A MEU CLB (with organizational and intermediate supply and maintenance, landing support, engineering, communications, motor transport, medical, and other combat service support capabilities).
- Other critical enablers and maneuver elements assigned from the Marine expeditionary force information group (MIG) (e.g., radio battalion, intelligence battalion) or external organizations (e.g., naval mobile construction battalion air detachments).
A notional MEU CE structure is displayed in figure 1-5 on page 1-8. A MEU CE is employed as the organic C2 element of the MEU. It is capable of single site or split-based operations and can self-sustain for up to 15 days. The MEU CE may also be employed for a limited period as the forward/tactical C2 echelon of a JTF headquarters or a larger MAGTF CE. Marine Forces Pacific and MARFORCOM maintain forward-deployed MEUs directed by their CE in the Mediterranean Sea, the Western Pacific, the Indian Ocean, and/or Arabian Gulf region, as required by the President. The MEU is a self-contained operating force capable of missions of limited scope and duration and as a forward-deployed extension of the MEF. Generally, MEUs undergo an extensive, 26-week predeployment training program that includes time to prepare to execute missions across a range of military operations within 6 hours of notification.

## Chapter 6 Marine Aircraft Wing

Marine Corps aviation is organized, trained, and equipped to provide a task-organized ACE for any size MAGTF. The ACE is not a formal command. The term "ACE" categorizes the functionality of specific forces within the MAGTF. For any MAGTF, the ACE is composed of task-organized Marine aviation forces under a single commander. The ACE commander is the MAGTF commander's principal advisor and subject matter expert on all aviation activities. The ACE is postured to operate from a variety of sea- and shore-based facilities to support all phases of MAGTF, joint, and multinational expeditionary operations. The primary focus of the ACE is to support the MAGTF during the assault landing phase and subsequent operations ashore. Air support is furnished by Marine aircraft squadrons operating from forward operating bases (FOBs), amphibious shipping, or by aircraft operating from aircraft carriers that are within striking distance of the amphibious objective area.

## Marine Aircraft Wing Functions

The MAW is organized to provide flexible and balanced aviation organizations that provide the full range of aviation operations. The MAW provides personnel and equipment for a MAGTF ACE. Operationally, an ACE task-organizes with various resources from within the MAW to complete the ACE's assigned mission using a MAW's inherent capability of performing all of the six functions of Marine aviation: offensive air support (OAS), antiair warfare (AAW), assault support, air reconnaissance, electronic warfare, and control of aircraft and missiles. Marine aviation organizations that are smaller than a MAW provide the requisite functions through scaled task organization.

## Offensive Air Support

Offensive air support is air operations against enemy installations, facilities, and personnel to assist the accomplishment of MAGTF objectives by the destruction of enemy resources or the isolation of the enemy force. Offensive air support includes the categories of close air support (CAS) and deep air support.

Close Air Support. Close air support is "air action by manned or unmanned fixed-wing and rotary-wing aircraft against hostile targets that are in close proximity to friendly forces and that require detailed integration of each air mission with the fire and movement of those forces." (DOD Dictionary of Military and Associated Terms, hereafter referred to as *DOD Dictionary*). This detailed integration is accomplished using positive control. Terminal controllers provide positive control.

Deep Air Support. Deep air support 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 1-10.2, Marine Corps Supplement to the DOD Dictionary of Military and Associated Terms) Deep air support missions include air interdiction, armed reconnaissance (AR), and strike coordination and reconnaissance (SCAR).

Air Interdiction Missions. "Air operations conducted to divert, disrupt, delay, or destroy the enemy's military surface capabilities before it can be brought to bear effectively against friendly forces, or to otherwise achieve objectives that are conducted at such distances from friendly forces that detailed integration of each air mission with the fire and movement of friendly forces is not required." (*DOD Dictionary*) These missions respond to known targets briefed in advance.

Armed Reconnaissance Missions. The AR missions locate and attack targets of opportunity (i.e., enemy materiel, personnel, and facilities) in assigned areas. Armed reconnaissance differs from air interdiction because AR target's locations are not known or briefed in advance. Armed reconnaissance provides the MAGTF commander an economy of force to cover and defend terrain not suited to other forces.

Strike Coordination and Reconnaissance Missions. The SCAR missions are closely linked with AR missions.

The SCAR missions detect, report, and coordinate or perform attack or reconnaissance of targets. The SCAR aircraft may discover enemy targets and provide a target mark or talk-on for other AR missions or accurately locate targets for air interdiction missions. The SCAR missions can be flown by any AR aircraft that has been assigned an area to coordinate the attacks of other deep air support flights.

## Antiair Warfare

Antiair warfare integrates offensive and defensive operations to attain and maintain a desired degree of air superiority and protection by neutralizing or destroying enemy aircraft and missiles, both before and after launch to ensure friendly freedom of action, provide protection, and deny enemy freedom of action. Antiair operations may use the range of military capabilities to neutralize or destroy enemy aircraft, missiles, and launchers before and after launch. Generally, offensive counterair operations seek to dominate enemy airspace and prevent the launch of threats, while defensive counterair operations defeat enemy air and missile threats attempting to penetrate or attack through friendly airspace.

## 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 AO, in-flight refueling, and evacuation of personnel and cargo. The tasks of assault support fall within the following seven categories:

- Combat assault transport.
- Air delivery. - Air refueling. - Air evacuation. - Tactical recovery of aircraft and personnel. - Air logistical support. - Battlefield illumination.

## Air Reconnaissance

Air reconnaissance is operations undertaken to obtain information, by visual observation or other detection methods, about the activities and resources of an enemy or adversary via air vehicles.

## Electronic Warfare

Electronic warfare is "military action involving the use of electromagnetic and directed energy to control the electromagnetic spectrum and/or to attack enemy forces." (*MCRP 1-10.2*)

## Control Of Aircraft And Missiles

The control of aircraft and missiles function serves to integrate the activities of the other five functions of Marine aviation into a coordinated employment effort of facilities, equipment, communications, procedures, and personnel that allows the ACE commander to plan, direct, and control the efforts of the ACE in support of MAGTF's mission. Control of aircraft and missiles is executed through the Marine air command and control system (MACCS).

## Marine Aviation Organization

Organizationally, Marine aviation is divided into three active duty MAWs (see figs. 6-1, 6-2, and 6-3 on pages 6-4, 6-5, and 6-6, respectively) and one Reserve Component MAW (see fig. 12-1 on page 12-1). For command and control, a MAW contains Marine wing headquarters squadron (MWHS), a Marine air control group (MACG), and several MAGs. A MEF-sized MAGTF will be supported by an ACE that can be composed of up to two MAWs. A MAW may be reinforced by units from adjacent MAWs. A MEB-sized MAGTF will be supported by one or more MAGs and/or a task-organized MAG or MAG (reinforced). A MEU-sized MAGTF is supported by a medium-lift RW squadron (reinforced) that usually consists of RW aircraft and V/STOL, a MACG detachment, a FW MALS detachment, a RW MALS detachment, and previously established MWSS personnel. A SPMAGTF ACE will be sized and organized in accordance with the SPMAGTF's assigned mission.

## Marine Aircraft Wing Headquarters

The MAW headquarters directs and coordinates the operations of the MAW and it is organized into individual departments capable of performing the broad range of required staff functions. The MAW headquarters will be employed with the ACE where it may function in either a senior or subordinate staff role and can be task-organized as the ACE headquarters of a MEF to provide all functions of Marine aviation.

## Marine Wing Headquarters Squadron

The MWHS provides command and control, administrative, and supply support for a MAW headquarters. The MWHS, which will normally function as an integral unit structured subordinately to the MAW headquarters, provides administrative and staff support for wing headquarters

## Marine Air Control Group

The MACG provides, operates, and maintains the MACCS. The MACG contains subordinate units that provide the major agencies of the MACCS. The MACG normally consists of a Marine tactical air command squadron (MTACS), a Marine air support squadron (MASS), a Marine air control squadron (MACS), a low altitude air defense (LAAD) battalion, and a Marine wing communications squadron (MWCS). The MACG structure is displayed in figures 6-1, 6-2, and 6-3 (on pages 6-4, 6-5, and 6-6, respectively).

The Marine tactical air command center (TACC), which is furnished by MTACS, is the senior air C2 agency. The other major air control agencies are the tactical air operations center (TAOC), furnished by MACS, and the direct air support center (DASC), furnished by MASS. Additionally, the MACS provides air traffic control (ATC) facilities and the LAAD battalion provides the MAGTF's organic surface-toair weapons.

## Marine Air Control Group Headquarters

The MACG headquarters coordinates all aspects of air command and control and air defense within the MAW and provide the command and staff functions for the MACG commander when deployed as part of the MAGTF ACE. The MACG headquarters is organized into departments commensurate with command and staff functions. It is employed with the combined assets of the MACG as a component of the ACE, normally at the MEF or MEB level. Before establishing a MEF, in conjunction with MAGTF task organization, specific MACG headquarters personnel may be required to augment the MTACS.

## Marine Tactical Air Command Squadron

The MTACS is structured as an organic unit subordinate to the MACG that provides equipment, and maintenance, as well as installs and maintains associated automated systems for the Marine TACC. Specifically, MTACS equips, staffs, operates, and maintains the Marine TACC current operations section and provides and maintains future operations and future planning facilities. The MTACS can furnish a Marine TACC capability of up to the size that supports a MEF-level ACE to meet operational requirements deemed necessary by the MAGTF commander.

## Marine Air Support Squadron

The MASS is structured as an organic unit subordinate to the MACG that provides equipment, and maintenance, as well as installs and maintains associated automated systems for the ACE DASC. The DASC provides control and coordination capabilities of FW and RW aircraft operating in direct support of MAGTF forces. It supports, controls, coordinates, and integrates direct air support operations in support of naval expeditionary, joint, and multinational operations.

## Marine Air Control Squadron

The MACS is structured as an organic unit subordinate to the MACG that provides equipment, and maintenance, as well as installs and maintains associated automated systems for the ACE TAOC. It provides air surveillance and control of aircraft and surface-to-air weapons as well as continuous all-weather radar and nonradar ATC services. The MACS consists of a squadron headquarters, a TAOC detachment, at least two ATC detachments, and an early warning/control (EW/C) detachment. The MACS is organized and equipped for employment in the ACE. The TAOC, ATC, and EW/C detachments, when augmented by the appropriate headquarters elements, may be deployed separately to provide air control, ATC, and EW/C support for vital areas of a MAGTF.

## Low Altitude Air Defense Battalion

Primarily, the LAAD battalion provides close-in, low-altitude, surface-to-air weapons fires in defense of MAGTF assets. It defends forward combat areas, maneuver forces, vital areas, installations, and/or units engaged in special/independent operations. Subordinately, the LAAD provides task-organized ground security forces in defense of MAGTF air sites. The LAAD battalion consists of a battalion headquarters, an H&S battery, and two firing batteries. The H&S battery is divided into an H&S battery (minus) and an H&S battery detachment. Additionally, the H&S battery facilitates the logistical support of separately deployed firing batteries. The LAAD battalion is normally employed within the MEF's integrated air defense system.

## Marine Wing Communications Squadron

The mission of the MWCS is to provide expeditionary communications for the ACE of a MEF, including the phased deployment of task-organized elements. The MWCS consists of a headquarters element and at least two MWCS detachments. It is employed in order to provide communications support for the ACE headquarters and Marine TACC. Each MWCS detachment may be independently deployed to provide external communications for up to two airfields and four FOBs.

## Marine Aircraft Group

The mission of the MAG is to provide the staff support necessary for the effective command of subordinate squadrons of the MAG. It is usually composed of functionally similar aircraft squadrons and their support units. There are two basic types of MAGs: RW and FW (see figs. 6-1, 6-2, and 6-3 on pages 6-4, 6-5, and 6-6, respectively). The primary mission of the RW MAG is to provide assault support. Normally, RW MAGs include the following:

- HMLAs.
- VMMs. - HMHs. - MALS RW.
The primary mission of a FW MAG is to conduct AAW and OAS operations from advance bases, FOBs, and aircraft carriers. Fixed-wing MAGs may consist of any combination of the following:

- VMA.
- Marine fighter/attack squadron (VMFA). - Marine fighter/attack (all-weather) squadron (VMFA[AW]). - Marine aerial refueler transport squadron (VMGR). - VMU. - MALS FW.
The MAG is scaled, tailored, and task-organized for its assigned mission within the MAGTF. The MAG is the smallest aviation unit that is designed for independent operations with no outside assistance except access to a source of supply.

## Marine Aircraft Group Headquarters

The mission of the MAG headquarters is to provide staff support to command MAG subordinate squadrons effectively. The MAG headquarters is organized to perform the broad range of required staff functions and is employed with the ACE, where it may function in a senior or subordinate staff role.

## Marine Aviation Logistics Squadron: Fixed-Wing/Rotary-Wing

The mission of a MALS is to provide aviation logistic support, guidance, and direction to MAG squadrons on behalf of the commanding officer and logistic support for Navy-funded equipment in the supporting MACG and MAW. The MALS is organized as a core unit that is supplemented by aircraft-specific and MACS augmentees. This concept allows the squadron to provide logistical support to the MAG's aircraft squadrons and MACGs in garrison or as a task-organized ACE. The MALS is employed as an integral unit of a MAG within an ACE or can provide elements/support packages to another MALS that is supporting a MAGTF ACE.

## Marine Aerial Refueler Transport Squadron

The mission of the VMGR is to provide air refueling service in support of air operations and assault air transport of personnel, equipment, and supplies. The VMGR can function as an integral unit or as separate detachments. Two detachments within the squadron organization provide the capability to conduct dual-site operations and support simultaneous contingencies. The VMGR is normally employed in general support as directed by the MAGTF commander. The unit may be employed as an entire squadron or as a headquarters unit and two detachments capable of operations in three separate locations simultaneously.

## Marine Fighter/Attack Squadron

The mission of the VMFA is to intercept and destroy enemy aircraft under all-weather conditions and attack and destroy surface targets. Each VMFA normally functions as an integral unit and is structured to operate as a subordinate unit of an ACE.

## Marine Fighter/Attack (All-Weather) Squadron

The MWSS will normally function as an integral unit which is structured to operate as a MAG subordinate unit. Each MWSS functions as an integral unit of the ACE.

## Chapter 7 Marine Logistics Group

The MLG is responsible for providing tactical logistics above the organic capability of supported units to all elements of the MEF. In addition, the MLG provides supply chain management and a link to operational- and theater-level logistic agencies capable of supporting 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 MLG are structured to provide permanently organized subelements to support independently deployed battalions, regiments, MEUs (e.g., task-organized groups to provide support, as required and preplanned), or geographically separated units in garrison. The most significant attribute of the MLG is that it is a permanently organized command charged with the responsibility of providing all major tactical logistic functions for the MEF beyond the organic capabilities of the supported units/organizations. Thus, it is staffed and equipped by tables of organization and tables of equipment to support a one-division/one-wing MEF and/or three MEUs simultaneously. The mission of the MLG is to provide sustained tactical-level logistic support above the organic capabilities of supported elements of the MEF. The tasks of the MLG include

- Providing command, control, and coordination of MLG operations in support of the MEF.
- Providing direct support motor transport, intermediate-level supply coordination and limited support in
the areas of field-level maintenance, landing support, general engineering, and forward resuscitative health care capability to the MARDIV.
- Providing general support ground supply support, field-level maintenance support, and motor transport
support beyond supported units' organic capabilities to the MEF and designated MEBs.
- Providing authorized overflow crew/operator maintenance for Marine Corps-furnished ground
equipment of the MEF to include calibration, repair, modification, reclamation, recovery, and
evacuation assistance.
- Coordinating transportation and throughput support, beyond the supported units' organic capabilities
for the deployment and employment of the MEF to include transportation, landing support, port and terminal operations, air delivery, and materials handling equipment (MHE).
- Providing general engineering support to the MEF to include reconnaissance, construction of roads;
combat service support installations and other support facilities; vertical construction and maintenance of encampment and other personnel support facilities; demolition and obstacle removal; and augmentation for tasks beyond the organic engineering capabilities of supported units. Requirements for emplacement of standard and nonstandard bridging and rafting will be globally sourced as required to support this function.

The mission of the Marine Corps DIRINT is to oversee policy, plans, programming, budgets, and staff supervision of intelligence and supporting activities within the Marine Corps. The DIRINT supports the DC for Information and represents the Service in joint, DOD, and intelligence community matters. The Intelligence Department has Service staff responsibility for geospatial intelligence, SIGINT, electronic warfare, human intelligence, measurement and signature intelligence, and counterintelligence. It develops and implements the synchronized strategy for the Marine Corps intelligence, surveillance, and reconnaissance enterprise. The Intelligence Department is made up of the following three divisions, which are responsible for their areas of expertise:

- Information Intelligence Enterprise Branch. - Information Intelligence Strategy and Policy. - Marine Corps Intelligence Activity (MCIA).
Located at HQMC, the DIRINT is the Service cryptologic component chief and exercises OPCON over MCSB. The DIRINT also supervises the operation of MCIA. The mission of MCIA is to provide intelligence forecasts and analysis in support of Marine Corps planning and decision-making, doctrine and force structure development, systems and equipment acquisition, war-gaming, and training and education. The MCIA supports Marine Corps operating forces, DOD, the intelligence community, and allied partners by providing comprehensive intelligence for expeditionary mission sets. The MCIA facilitates the efforts of the Marine Corps Intelligence, Surveillance, and Reconnaissance Enterprise through coordinated planning, guidance, and IT. Due to the nature of its mission, MCIA is organized as both a Service intelligence production center and the focal point of coordination for production by the entire Marine Corps Intelligence, Surveillance, and Reconnaissance Enterprise. The MCIA supports current and future operations of the operating forces across the planning process and provides strategic forecasts upon which Marine Corps doctrine, organization, training/education, materiel, leadership/strategic communication, personnel, facilities, and cost planning is based. It also provides operational intelligence with which the operating forces develop training, exercises, plans, and, when necessary, surge and reachback capabilities to augment and support engaged forces on a tactical level. The MCIA is broadly organized on a functional basis. The Operations Directorate is organized and focused to plan and coordinate MCIA's efforts with those of the Marine Corps Intelligence, Surveillance, and Reconnaissance Enterprise. The production and analysis company is organized to provide strategic estimates to Marine Corps Service leadership and to be responsive to the needs of the Marine Corps components of the GCCs and deployed Marine Corps forces around the globe.

The commanding officer, MCIA maintains OPCON as well as discipline of assigned military personnel. The MCIA provides intelligence forecasts that identify potential future battlespaces, opportunities, and technologies that are likely to impact upon future Marine Corps operations. These forecasts and follow-on analytic support inform the MSC and the supporting establishment in developing doctrine, organization, training/education, materiel, leadership/strategic communication, personnel, facilities, and cost requirements and serve to shape the future of the operating forces. As trends become more evident and indicative, MCIA refines its forecasts into a mid-range threat assessment that identifies countries, regions, and transnational threats of concern. This establishes a priority for focused and deliberate collection and production with the intent of providing information and understanding to the operating force before a crisis emerges, conflict occurs, or an opportunity presents itself. The MCIA then coordinates and deconflicts intelligence activities throughout the Marine Corps Intelligence, Surveillance, and Reconnaissance Enterprise and DOD; intelligence community; and allied partners to develop intelligence packages for those regions where operating forces are likely to become engaged and those missions likely to be executed. As a crisis precipitates or an opportunity emerges, MCIA carries out deliberate production to satisfy priority intelligence requirements and resolve intelligence gaps in support of operating forces. During a crisis, MCIA provides surge and reachback support to Marine Corps operating forces to meet operational contingencies. Before, during, and after an engagement, MCIA serves as the primary exposure point for all products to the intelligence community by net-centric means.
