The symbology chapters of this manual focus primarily on land military symbols applicable for the Army and Marine Corps. In addition to terminology, this manual includes the following updated lists:

-
Approved acronyms and abbreviations with their expansions.
-
Two-letter country codes.
-
Brevity codes and their meanings.
-
Procedural words.
-
Tactical tasks.

## Introduction

The terminology section of this manual is a compilation of doctrinally-accepted definitions that have been taken from approved manuals. One Army field manual is cited as the proponent or reference for each definition. (NOTE: As the US Army is in the process of changing the numbering system for its field manuals, the cited manual number reflects the number that was in effect at the time FM 1-02 was approved.) The proponent manual for all Marine Corps definitions in this publication is MCRP 5-12C, Marine Corps Supplement to the Department of Defense Dictionary of Military and Associated Terms.

Terminology entries in this manual fall into the following five categories:
- Definitions that are applicable to the US Army only. The definition is preceded by
"(Army)" and followed by the proponent US Army field manual in parentheses:
situational understanding - (Army) The product of applying analysis and judgment to the common operational picture to determine the relationship among the factors of METT-TC. (FM 3-0)

- Definitions that are applicable to the US Marine Corps only. The definition is preceded by
"(Marine Corps)":
situational awareness - (Marine Corps) Knowledge and understanding of the current situation which promotes timely, relevant, and accurate assessment of friendly, enemy, and other operations within the battlespace in order to facilitate decisionmaking. An informational perspective and skill that fosters an ability to determine quickly the context and relevance of events that are unfolding.

- Definitions that are applicable to both the US Army and US Marine Corps. The definition
follows the term directly, and the proponent Army manual follows the definition:
actions on contact - A series of combat actions, often conducted simultaneously, taken upon contact with the enemy to develop the situation. (FM 3-90)
In some cases the Army and Marine Corps have agreed on a compromise definition for a particular term. This definition does not appear in either Service's manuals, but will be incorporated into them when the appropriate manuals are revised. In such cases the definition is preceded by "(Army/Marine Corps)" and followed by the proponent Army manual:
route reconnaissance - (Army/Marine Corps) A directed effort to obtain detailed information of a specified route and all terrain from which the enemy could influence movement along that route. (FM 3-90)

- Joint and/or NATO terms whose definitions are applicable to the Army and Marine Corps
as well. Joint and NATO definitions are reproduced exactly as they appear in JP 1-02 (12 April 2001, as amended through 05 June 2003) and AAP-6 (2003) respectively. The definition is preceded by one of four possible parenthetical notations (see below). "See FM
XX" follows the definition, signifying that the indicated manual is the reference manual for Army-specific usage:

 (DOD): the term is a joint term.
persistent agent - (DOD) A chemical agent that, when released, remains able to cause casualties for more than 24 hours to several days or weeks. See FM 3-9.

 (NATO): the term is a NATO term.
reference box - (NATO) The identification box placed in the margin of a map or chart which contains the series designation, sheet number and edition number in a readily identifiable form. See FM 3-25.26.

 (DOD, NATO): the term is both a joint and NATO term, and the joint and
NATO definitions are virtually the same (with minor differences noted).
combat power - (DOD, NATO) The total means of destructive and/or disruptive force which a military unit/formation can apply against the opponent at a given time. See FM 3-0.

state of readiness - state 2 - armed - (DOD, NATO) The state of a demolition target in which the demolition charges are in place, the firing and priming circuits are installed and complete, and the charge is ready for immediate firing. [Note: the NATO definition does not include "and the charge is."] See FM 5-250.

 (DOD).... [Note: see AAP-6]: the term is both a joint and NATO term. The
definitions are similar in meaning, but the wording is different. If the reader requires the exact NATO definition, he should consult AAP-6 (most current edition), *NATO Glossary of Terms and Definitions*.
immediate decontamination - (DOD) Decontamination carried out by individuals immediately upon becoming contaminated. It is performed in an effort to minimize casualties, save lives, and limit the spread of contamination. [Note: See AAP-6.] See FM 3-5.

- Joint/NATO terms that are used by the Army/Marine Corps, but whose definitions are either inadequate for or not applicable to specific Army/Marine Corps usage. Both the joint and NATO definitions and the Service definitions are given. Where Army and Marine Corps definitions differ from each other, both are provided. The Army definition is followed by the proponent manual.
seize - (DOD) To employ combat forces to occupy physically and control a designated area. (Army) A tactical mission task that involves taking possession of a designated area using overwhelming force. (FM 3-90) (Marine Corps) To clear a designated area and obtain control of it.

If the term is a joint/NATO term, but no Army field manual is referenced, then this indicates that the Marine Corps has proponency for the term and definition:
action phase - (DOD) In an amphibious operation, the period of time between the arrival of the landing forces of the amphibious force in the operational area and the accomplishment of their mission. See also amphibious force; **amphibious operation**;
landing force; **mission**.

In addition, there are two further descriptors that may appear after a definition:
- "Also called": If the term has an accepted abbreviation or acronym, the abbreviation or acronym appears bolded after the definition, preceded by "Also called":
passage point - A specifically designated place where the passing units will pass through the stationary unit. Also called PP. (FM 3-90)

- "See also": If there are any related terms defined elsewhere in the manual, they are crossreferenced at the end of the definition as bolded terms preceded by "See also":
hostile criteria - Description of conditions under which an aircraft or a vehicle may be identified as hostile for engagement purposes. See also hostile acts; rules of engagement. (FM 27-10)
The symbology section is broken down into chapters dealing with unit symbols, equipment symbols, graphic control measures, installation symbols, and stability operations and support operations symbols. Each of these chapters provides detailed requirements for composing and constructing its associated symbols and control measures. While the manual does not include every possible symbol for every possible context, the rules for building a specific set of military symbols allow enough flexibility for users to create any symbol to meet their operational needs. This manual contains a compilation of graphic control measures. This revision includes information on building symbols and using graphics omitted in the 1997 version that appeared in earlier versions of military symbology manuals. It includes a link between terms and symbols with the cross-referenced terms, including the proponent manual that provides the description for the usage of the graphic control measures. All graphic control measures in this manual are linked to doctrine.

fire support coordination line - (DOD) A fire support coordinating measure that is
established and adjusted by appropriate land or amphibious force commanders within their boundaries in consultation with superior, subordinate, supporting, and affected commanders. Fire support coordination lines (FSCLs) facilitate the expeditious attack of surface targets of opportunity beyond the coordinating measure. An FSCL does not divide the area of operations by defining a boundary between close and deep operations or a zone for close air support. The FSCL applies to all fires of air, land, and sea-based weapons systems using any type of ammunition. Forces attacking targets beyond an FSCL must inform all affected commanders in sufficient time to allow necessary reaction to avoid fratricide. Supporting elements attacking targets beyond the FSCL must ensure that the attack will not produce
adverse effects on, or to the rear of, the line. Short of an FSCL, all air-to-ground and surfaceto-surface attack operations are controlled by the appropriate land or amphibious force commander. The FSCL should follow well-defined terrain features. Coordination of attacks beyond the FSCL is especially critical to commanders of air, land, and special operations forces. In exceptional circumstances, the inability to conduct this coordination will not
preclude the attack of targets beyond the FSCL. However, failure to do so may increase the risk of fratricide and could waste limited resources. (NATO) Within an assigned area of operations, a line established by a land or amphibious force commander to denote coordination requirements for fires by other force elements which may affect the commander's current and planned operations. The fire support coordination line applies to
fires of air, ground or sea weapons using any type of ammunition against surface or ground targets. The establishment of the fire support coordination line must be coordinated with the appropriate commanders and supporting elements. Attacks against surface or ground targets short of the fire support coordination line must be conducted under the positive control or procedural clearance of the associated land or amphibious force commander. Unless in exceptional circumstances, commanders of forces attacking targets beyond the fire support coordination line must coordinate with all affected commanders in order to avoid fratricide and to harmonize joint objectives. Note: in the context of this definition, the term "surface targets" applies to those in littoral or inland waters within the designated area of operations. Also called **FSCL**.

separated from an object to ensure no more than a 10 percent chance of damage with a 99
percent assurance. It is the sum of the radius of preclusion and the buffer distance. Also called LSD. See also desired ground zero; **minimum safe distance**. (FM 100-30)
level of care Describes the five levels of treatment within the military health care system.
Each level has the same capabilities as the level before it, but adds a new treatment capability that distinguishes it from the previous level. **Level I:** The first medical care a
soldier receives is provided at this level. This care includes immediate lifesaving measures, emergency medical treatment, advanced trauma management (ATM), disease prevention, stress prevention, casualty collection, and evacuation from supported unit to supporting medical treatment facility (MTF). Level I elements are found in divisions, corps, and in echelons above corps (EAC) units. These elements include the trauma specialist assisted by first aid (self-aid/buddy aid) and enhanced first aid (combat lifesaver) and the Level I MTF
(battalion aid station). Some or all of these elements are found in maneuver, combat support, and combat service support units. When a Level I medical capability is not present in a unit, this support is provided, on an area support basis, to that unit by the supporting Level II medical unit. **Level II:** Capabilities duplicate Level I and expand available services by adding operational dental care, laboratory, x-ray, and patient holding capabilities. Some Level II facilities also have mental health and preventive medicine capabilities. Emergency medical treatment and ATM is continued. If necessary, additional emergency measures are instituted; however, these measures do not exceed those dictated by the immediate needs. Level II units are located in the combat zone (brigade, division, corps support areas) and at EAC. Forward support, brigade support, main support, division support, area support medical companies, and medical troops provide Level II medical care. The forward surgical team (FST) from the corps collocates with a medical company/troop and provides emergency resuscitative surgical capability. The combined medical company and FST are generally considered to be Level II+. This capability is organic to the medical company/troop, main support battalion, division support command, airborne and air assault divisions, and the support squadron, armor cavalry regiment (light). **Level III:** This level of support expands the support provided at Level II. Level III characterizes the care that is provided by the combat support hospital (CSH) in the corps. Minimum operational functions required for a Level III hospital include: command, control, and communications; patient administration; nutritional care; supply and services; triage; emergency medical treatment; pre-operative care; orthopedics; general surgery; operating rooms and central materiel and supply services;
anesthesia, nursing services (to include intensive and intermediate care wards); pharmacy; clinical laboratory and blood banking; radiology services; and hospital ministry team services. Operational conditions may require Level III units to locate in offshore support facilities, third country support bases, or in other locations. Level III hospitalization provides hospital care to all classes of patients and with medical resupply can indefinitely sustain care. The Level III hospital in some environments may be augmented with specialty teams, such as head and neck or renal hemodialysis team. **Level IV:** This level of care is provided at an EAC CSH that is normally augmented with additional and specialized medical and surgical capabilities and with additional patient holding capabilities. The EAC CSH is staffed and equipped for general and specialized medical and surgical treatment. This level of care provides further treatment to stabilize those patients requiring evacuation to continental United States (CONUS). **Level V** (CONUS Support Base): This definitive level of care is provided in the CONUS support base. The patient is treated in hospitals staffed and equipped to provide the most definitive care available. Hospitals used to provide this care are not limited to US Army hospitals. Hospitals from the other Military Services, the Department of Veterans Affairs, and the civilian health care systems may also be included. Civilian hospitals include those hospitals that are members of the National Disaster Medical Systems. (FM 4-02)

This chapter implements STANAG 2019, STANAG 2022, QSTAG 509, and QSTAG 511.

## Chapter 4 Military Symbols

A military symbol is a graphic representation of units, equipment, installations, control measures, and other elements relevant to military operations. As a part of doctrine, these symbols provide a common visual language for all users. Standardization of military symbols is essential if operational information is to be passed among military units without misunderstanding. This chapter defines the single standard used to develop and depict hand-drawn and computer-generated military symbols for situation maps, overlays, and annotated aerial photographs for all types of military operations. It provides rules for building specific sets of military symbols. These rules provide details of construction, but allow enough flexibility for the user to build symbols to meet operational needs.

## Purpose

4-1. The main purpose of military symbology is to allow commanders and staffs to graphically display certain elements of the operational picture. Situation maps, overlays, and annotated aerial photographs are used to express an operation plan or order, concept, or friendly or hostile (enemy) situation. The combination of unit and equipment symbols and control measures, as well as other military symbols, creates an indispensable tool for quickly portraying military operations.

This manual primarily focuses on land military symbols. Chapter 4 discusses a single standard for military symbols. For detailed requirements for the composition and construction of symbols and control measures, see

-
Chapter 5, Unit Symbols.
-
Chapter 6, Equipment Symbols.
-
Chapter 7, Graphic Control Measures.
-
Chapter 8, Installation Symbols.
-
Chapter 9, Stability Operations and Support Operations Symbols.
Where applicable, links are provided between symbols and terms for greater understanding. The Army field manuals referenced with the terms provide an explanation of how those terms are used. The symbology defined in this manual is in compliance with Department of Defense Military Standard 2525, *Common Warfighting Symbology*.

## Orientation Of Military Symbols

4-2. All the military symbols in this manual are designed to be displayed with a single orientation. The symbols will be displayed with the top of the symbol pointed north.

## Composition Of Military Symbols

4-3. A military symbol is composed of a frame, color (fill), icon(s), and may include text or graphic modifiers that provide additional information (see figure 4-1.) Included in military symbols are graphic control measures, which are composed of boundaries; lines; areas; points; targets; and nuclear, biological, or chemical attacks/events. The composition of graphic control measures varies from that of unit, equipment, installation, and support operations and stability operations symbols. Graphic control measures have the same attributes as other military symbols, but utilize different rules for building. The details for building graphic control measures are provided in chapter 7 of this manual.

## Frame

4-4. The frame is the geometric border of a military symbol. It represents affiliation, dimension, and status. The frame serves as the base to which the other components of the symbol are added. A frame can be black or colored, depending on the system being used for representation (see color paragraph below). The frame may include modifiers (U or ?) that are placed inside or outside the frame that help determine affiliation. These modifiers are considered to be an integral part of the frame.


Affiliation. Affiliation refers to the relationship of the symbol being represented to friendly forces. The affiliation categories are friend, assumed friend, hostile, suspect, neutral, unknown, and pending. (The frame shapes for affiliation are shown in table 4-1.)

Dimension. Dimension refers to the primary mission area for the symbol being represented. There are five dimensions that can be represented: land, sea
surface, sea subsurface, air and space, and unknown. Normally, if the dimension cannot or has not been determined, it is considered to be unknown. This manual focuses on the land dimension (see table 4-1).

Status. Status refers to whether a unit is known to be present at the location identified or whether it is a planned or suspected location. Regardless of affiliation, present status is indicated by a solid line and planned or suspected status is indicated by a dashed line (see table 4-2).

COLOR (FILL)

4-5. Color indicates affiliation. Color is the hue of the line marking the geometric border or the fill of the interior area of the frame. Table 4-3 depicts the default colors that are used to designate colored symbols for either hand-drawn or computer-generated displays. The use of any colors other than those in table 4-3 for military symbols must be explained in an accompanying legend.

## Icon

4-6. The icon is the innermost part of the military symbol providing an abstract pictorial or alphanumeric representation of the function or role of the military symbol. Within the frame and as an integral part of a basic icon, there may also be additional graphic or text modifiers that further define the function or role of the military symbol being displayed. See chapters 4, 5, 7, and 8 for application and examples.

## Text Or Graphic Modifiers

4-7. A text or graphic modifier provides additional information about a symbol. This information is displayed on the outside of the frame. The default placement of modifiers in fields around the frame is shown in figure 4-2. The placement of these modifiers is the same, regardless of frame shape.

4-8. The field entries in table 4-4 correspond with the field positions in figure 4-2. This table includes all entries used for military symbols. Selected portions of this table are reproduced in chapters 5, 6, 7, 8, and 9 for easy reference in building symbols. For many of the fields in table 4-4, specific entries are found in chapters 5, 6, 7, 8, and 9.

4-9. For information on building air, sea surface, sea subsurface, and space military symbols, refer to Military Standard 2525. The rules for the construction of these military symbols are identical to those for land symbols. All the frame shapes that are used with each of the domains: air, land, sea surface, sea subsurface, and space can be found in table 4-1, page 4-3. This also provides a reference for users of this manual to understand how land symbology fits into joint symbology. Selected parts of the land portions of table 4-1, page 4-3, are reproduced in chapters 4, 5, 7, and 8 as necessary for the construction of those symbols and the understanding of building symbols.

## Basic Rules For Building Symbols

4-10. When building symbols as described in chapters 5 through 7, follow the basic rules:


Use existing symbols or modifiers whenever possible as building blocks for new symbols.

Symbols must be usable in both hand-drawn and computer-generated automated modes.

Symbols must be easily distinguishable so as not to be confused with other symbols.

Friendly symbols must not use attributes that could be confused with enemy symbols.

Symbols must be distinguishable without color for use on a monochrome display.

Composite symbols will generally have the primary symbol centered above or below the modifying symbols.
4-11. All symbols will be drawn or portrayed with the top of the symbol facing the top of the overlay (normally north is at the top). Orientation of the symbol will be accomplished by using the "Q" field for moving symbols or another graphic such as a battle position or support by fire position.

This chapter implements STANAG 2961.

## Chapter 5 Unit Symbols

This chapter establishes a single standard for developing land unit symbols. A unit is a military element whose structure is prescribed by a competent authority. This chapter includes a wide variety of unit symbols and modifiers for building new or unique symbols. However, no attempt to depict all unit symbols has been made. Rather, a standard method for constructing unit symbols is presented. Once the user is familiar with the prescribed system, any desired unit can be developed using the logical sequence provided in this chapter. The symbols shown in this chapter are adequate for depicting hostile units. When representing unorthodox units, select the most appropriate symbol contained herein. Avoid using any symbols, or combinations and modifications of symbols, that differ from those in this manual. If, after searching doctrinal symbols and modifiers, it is necessary to create a new symbol, explain the symbol in an accompanying legend. Computer-generated systems may have difficulty in passing nonstandard symbols.

## Composition Of Unit Symbols

vice of the Army/Marine Corps) or functional symbols (icon), and text and/or other symbol modifiers (figure 5-1). (See table 5-1 for the steps used to build unit symbols.)

| Step #    | Step    | Example    |
|-----------|---------|------------|
Step 1.
First choose the frame that matches the affiliation of the unit (friendly, hostile, neutral). Then choose branch or functional symbol for field "A" (see figure 5-2, page 5- 3; table 5-2, page 5-4; and table 5-3, page 5-6). In this example, the affiliation is
friendly and the branch is infantry. (See the
following land unit frame shapes and affiliations.)

Step 2.
If required , choose the second (additional) branch symbol modifier that further explains the capability of that unit, modifying field "A." In this example, the branch symbol modifier is "mechanized" or "armored" (see table 5-3, page 5-10).
Step 3.
Again, if required, choose third branch symbol modifier for the next capability, for field "A." In this example, the third function or capability is "wheeled" or more
appropriately "wheeled armored vehicle." This is a mobility modifier. It describes the capability of the unit to move personnel and equipment (see table 5-4, page 5-26).
Step 4.
Choose a fourth branch symbol modifier for any other capability, for field "A." In this example, the fourth function or capability is "gun system equipped." It is possible to have additional symbol modifiers; however, for this example, no further functional or capability modifiers are provided (see table 5-4, page 5-26).
| Step #                                       |
|----------------------------------------------|
| Step 5.                                      |
| Choose the text or graphic modifiers as      |
| necessary to provide further amplifying      |
| information. In this example, the graphic    |
| modifier is the echelon symbol, or field "B" |
| for a battalion (see table 5-6, page 5-33).  |

## Unit Symbol Modifier Fields

5-2. Figure 5-2 shows the placement of unit labeling fields around the friendly land unit symbol frame. The placement of unit symbol modifier fields is the same regardless of frame shape or affiliation. 5-3. Table 5-2 provides a description of each of the unit symbol modifier fields as shown in figure 5-2. See appendix B for examples of unit symbols with multiple fields that are filled in.

1 For those units designated under the Combat Arms Regimental System (CARS), both the battalion (or squadron) and traditional regimental numbers are shown. To avoid confusion with different levels of command, both numerical designations of the CARS units are always written together and separated by a dash (-) rather than a slash (/). AR 600-82, The US Army Regimental System, provides a listing of CARS units.

5-5. There is also a separate echelon known as a command. A command is a unit or units, an organization, or an area under the command of one individual. It does not correspond to any of the other echelons. It is designated by using ++ as its echelon symbol (see figure 5-3).

## Field D: Task Force

5-6. A task force is a temporary grouping of units, under one commander, formed for carrying out a specific operation or mission or a semi-permanent organization of units, under one commander, formed for the purpose of carrying out a continuing specified task (see figure 5-4).

## Field F: Reinforced Or Detached

5-7. These symbols are used at division and below levels. The reinforced symbol + indicates that the capability of one unit has been augmented by the capability of another unit. The reduced symbol - indicates that the capability of a unit has been reduced by the detachment of one or more of its units. If a unit has been both reinforced and reduced, then the + symbol is used (see figure 5-5).


_____________________________________________________________________ Unit Symbols

## Locating Unit Symbols

5-8. The center of mass of the unit symbol indicates the general vicinity of the center of mass of the unit. To indicate precise location or reduce clutter in an area with multiple units, a line (without an arrow) extends from the center of the bottom of the frame to the unit location displayed as field Q. The line may be extended or bent as required. If a group of units (or installations) other than a headquarters is at one location, the grouping of the symbols may be enclosed with a bracket and the exact location indicated by a line from the center of the bracket (see figure 5-6).

5-9. Headquarters unit symbols include a staff or line drawn from the bottom left hand corner displayed as field "S." This staff may be bent or extended as required to indicate unit location. If several headquarters are at one location, more than one headquarters can be on a single staff. The highest echelon headquarters is placed on top, followed by the next levels in descending order (see figure 5-7).

## Chapter 6 Equipment Symbols

This chapter establishes a single standard for the development of equipment symbols. It describes procedures for creating composite weapon system symbols and the procedures for text labeling to provide necessary details.

## Orientation Of Equipment Symbols

6-1. Orientation of the symbols shown in this chapter is extremely important. All manual and automated displays and overlays should show the symbol oriented the same as the actual equipment. The "Q" field shows the orientation of moving equipment symbols. On color displays, blue or black represent friendly equipment, while red represents hostile equipment. Monochrome displays use the color available.

## Composition Of Equipment Symbols

6-2. An equipment symbol is composed of a frame, color (fill), equipment symbol (icon), and text or graphic modifiers (see figure 6-1). (See table 6-1 for the steps used to build equipment symbols.)

## Building Equipment Symbols

Note: The use of symbol frames, shown in table 6-1, is optional for equipment and recommended only for ships, aircraft, and aerial vehicles or monochrome screens.

| Step #    | Step    | Example    |
|-----------|---------|------------|
Step 1.
First choose the frame that matches the
affiliation of the equipment (friendly, hostile, neutral). Then choose the basic equipment symbol for field "A." In this example, the affiliation is friendly and the equipment is a howitzer. (See the following land equipment frame shapes and affiliations; see also figure 6- 2, page 6-4; table 6-3, page 6-4; and table 6-4,
page 6-7.)
Land Equipment Frame Shapes and Affiliation
Step 2.
Choose the size/range equipment symbol modifier that further explains the capability of
that equipment, modifying field "A." In this example, the equipment symbol modifier is
medium (bolded). (See table 6-4, page 6-7, and table 6-6, page 6-31.)
Step 3.
Choose the mobility indicator modifier for the next capability, for field "R." In this example, the mobility indicator is self-propelled or tracked (bolded). (See table 6-5, page 6-29.)
| Step #                                            |
|---------------------------------------------------|
| Step 4.                                           |
| Choose text modifiers as necessary to provide     |
| further amplifying information. In this example,  |
| the text modifier is the type of equipment (field |
| "V"), or M109A6, and the common identifier        |
| (field "AF"), or Paladin. (See table 6-3, page 6- |
| 4.)                                               |
| Friendly (M109A6 Paladin) Medium                  |
| Self-Propelled Howitzer                           |
| Step #                                             |
|----------------------------------------------------|
| Step 1.                                            |
| First choose the basic equipment symbol for field  |
| "A." In this example, the affiliation is friendly  |
| (black) and the equipment is a tank. (See table 6- |
| 4, page 6-19.)                                     |
Step 2.
Choose the size/range equipment symbol modifier that further explains the capability of that equipment, modifying field "A." In this example, the equipment symbol modifier is heavy. (See table 6-4, page 6-20, and table 6-6, page 6-31.)
Step 3.
If required, choose the mobility indicator modifier for the next capability, for field "R." In this example, there is no requirement for a mobility
indicator.
Step 4.
Choose text modifiers as necessary to provide further amplifying information. In this example, the text modifier is the type of equipment (field "V"), or M1A2, and the common identifier (field "AF"), or Abrams. (See table 6-3, page 6-4.)

## Equipment Symbol Modifier Fields

6-3. Figure 6-2 shows the placement of equipment labeling fields around the friendly land equipment symbol frame. The placement of equipment symbol modifier fields is the same regardless of frame shape or affiliation.

6-4. Table 6-3 provides a description of each of the equipment symbol modifier fields as shown in figure 6-2. See appendix B for examples of equipment symbols with multiple fields that are filled in.

## Size And Range Indicators

6-5. In building equipment symbols, horizontal or vertical lines are added for size and range indicators. If an equipment symbol has no lines, it is a basic equipment symbol. Adding one line designates it as light or short-range. Adding two lines designates it as medium or medium-range. Finally, adding three lines designates it as heavy or long-range. If a system is designated as greater than heavy or long-range, heavy or long-range indicators will be used.

## Chapter 7 Graphic Control Measures

Graphic control measures are graphic directives given by a commander to subordinate commanders to assign responsibilities, coordinate fire and maneuver, and control combat operations. They include boundaries; lines;
areas; points; targets; or nuclear, biological or chemical attacks/events.

Land graphic control measures are classified as maneuver, fire support, command and control, mobility/countermobility/survivability, and combat service support. This chapter establishes a standard system for the development and use of graphic control measures. These graphic control measures are the standard for all simulations, including those used in live, virtual, and constructive environments.

Note. For most graphic control measures, there is a corresponding definition in chapter 1. In an electronic copy, click on the page number to view the definition, then click on the corresponding page number to return to the graphic control measure. Included with the definition is the field manual that provides further information on the use of that graphic control measure.

## Overlays

7-1. Overlays are graphics drawn on top of a map, sketch, or photograph. To ensure accurate alignment, the overlay must have at least two reference marks at opposite locations. (FM 101-5 provides the minimum labeling requirements for an overlay.) On automated displays, overlays are graphical information that is joined electronically so it can be "turned on or off" over or in front of the primary digital display, such as a map, sketch, or photograph.

## Colors

7-2. When drawing manually or using a color computer-generated display, show all friendly graphic control measures in black. Show hostile graphic control measures in red. If red is not available, place the abbreviation "ENY" on the graphic in at least two places. If other colors are used to show friendly or hostile factions, use a legend to ensure understanding of the use of colors on the overlay. If neutral or unknown graphic control measures are included on the overlay, use green and yellow if available. If green and yellow are not available, draw neutral or unknown graphics in black and include the abbreviations of "NEU" for neutral or "UNK" for unknown. Draw all obstacles friendly, hostile, neutral, unknown or factionalusing green; if green is not available, draw obstacles using black. (Obstacle graphics are shown in the mobility and survivability section.)

## Orientation Of Control Measures

7-3. Most of the control measures in this chapter have a 360-degree orientation capability. Control measures are oriented to reflect their position on the ground. The labeling of those symbols is described in the next paragraph.

## Building Graphic Control Measures Labeling

7-4. Make all text labeling upper case letters. The reader should be able to read the labels for all text labels of modifier fields for graphic control measures when the bottom of the overlay is closest to the reader. Labeling written on an angle should be readable when the overlay is turned a quarter of a turn (90 degrees) clockwise (to the right) or counterclockwise (to the left). For boundaries, abbreviations of unit designations can be used when the abbreviation will not cause confusion. (See table 7-1 for the description of fields for text or graphic modifiers for boundaries. See table 7-2, page 7-5, for a list of abbreviations for unit designations.)

## Boundaries

7-5. For boundaries, place size markings perpendicular to the boundary line.

For all boundaries, use Arabic numerals to show the numbers of units, except for a corps boundaryuse Roman numerals to show the number of corps.

Figure 7-1 provides the orientation of boundary modifier fields for horizontal
(east/west) and vertical (north/south) boundaries. Figures 7-2 (page 7-3) through 7-5 (page 7-4) are examples of boundary symbols as they are used.

## Lines

7-6. Most lines should also be named as a phase line for easy reference during orders and radio transmissions. Mark phase lines as "PL (name)." Label other lines that have a specific purpose and are also named as phase lines (such as no-fire line, "NFL" ) on top of the line at both ends of the line inside the lateral boundaries, or as often as necessary for clarity. (See figure 7-6 for line modifier fields; figure 7-7 is an example of how line symbols are used. See table 7-3 for description of fields for text or graphic modifiers for lines.)

1For graphic control measures, two "W" fields can be used to indicate the effective time of that graphic control measure.

## Areas

7-7. Areas will normally be marked with the abbreviation for the type of area (see figure 7-8) followed by a name. Place this labeling in the center of the area unless the area is too small or the labeling would interfere with locating units (see figure 7-9). Not all fields are required for each area; some areas may use only one field, while others will use several. (See table 7-4 for description of fields for text or graphic modifiers for areas.)

1For graphic control measures, the two "W" fields can be used to indicate the effective time of that graphic control measure.

## Points

7-8. Most graphic control measure points are depicted as shown in figure 7-10. Supply points follow this format with a modification to the symbol. As with the symbol for supply units, there is an additional line placed toward the bottom of the box (see figure 7-11, page 7-9). However, there are other points (contact, coordination, decision, target) that are depicted differently. (See table 7-5, page 7-9, for description of fields for text or graphic modifiers for points.) The convention for depicting and labeling those points is shown in table 7-7, page 7-12, through table 7-17, page 7-62.

7-9. In building points, the name/type of the point is abbreviated and positioned inside the top part of the point symbol in field "A." For supply symbols, this may be a graphic depiction. In addition, below the abbreviation of the point name, the designation of the unit servicing that point can be included in field "T." To differentiate points, the point is numbered, lettered, or a combination. The number, letter, or combination is placed on the outside of the symbol on the right side at the top in field "T." On the outside of the point on the left side at the top and middle, date-time groups can be associated with the point. On the outside of the point at the top, additional information can be provided in field "H."

1For graphic control measures, the two "W" fields can be used to indicate the effective time of that graphic control measure.



## Fire Support Coordinating Measures

7-10. Label fire support coordinating measures with the effective times, the controlling headquarters, and the abbreviation of the control measure. Place this labeling on both ends of the line (see examples in figure 7-12 and figure 7-13) and repeat as often as necessary for clarity along any line that passes through many boundaries.



## Targets

7-11. Targets are labeled with target designator, target altitude, and target description (as shown in figure 7-14). Guidance on determining the lettering and numbering for target designators is found in FM 6-20-40.

## Nuclear, Biological, And Chemical Attacks/Events

7-12. Nuclear, biological, and chemical attacks/events are depicted as shown in figure 7-15 through figure 7-17. (See table 7-6, page 7-11, for a description of fields for text or graphic modifiers for nuclear, biological, and chemical attacks/events. For examples and descriptions of field entries for fire support control measures, see figure 7-6, page 7-6, and table 7-3, page 7-6, for lines and figure 7-8, page 7-7, and table 7-4, page 7-7, for areas.)

## Chapter 8 Installation Symbols

Installations are sites that incorporate permanent, semi-permanent, and temporary structures. This chapter establishes a single standard system for the development of a variety of installation symbols. Avoid using any symbols, or combinations and modifications of symbols different from those in this manual. If, after searching the doctrinal symbols and modifiers in this manual, a new symbol must be created, explain it in an accompanying legend.

## Composition Of Installation Symbols

8-1. An installation symbol is composed of a frame, color (fill), functional symbol(s) (icon), and text or graphic modifiers (figure 8-1). (See table 8-1, page 8-2, for the steps used to build installation symbols.)

| Step #                                       |
|----------------------------------------------|
| Step 1.                                      |
| First, choose the frame that matches the     |
| affiliation of the installation (friendly,   |
| hostile, neutral). Then choose a             |
| functional symbol for field "A." In this     |
| example, the affiliation is friendly and the |
| function is petroleum/gas/oil.               |
| Friendly Petroleum/Gas/Oil                   |
Steps 2-4.
Choose the second/third/fourth functional symbol modifier that further explains the capability of that installation, modifying field "A." In this example, the second functional symbol modifier is "aviation."
Step 5.
Choose text or graphic symbol modifier as necessary to provide further amplifying information. In this example, there are two text modifiers, the first is
installation composition (field "AI"), which is PRODUCTION/STORAGE, and the second is capacity of installation (field "K"), which is 100,000 gallons (100K GAL).

## Installation Symbol Modifier Fields

8-2. Figure 8-2 shows the placement of installation labeling fields around the friendly land installation symbol frame. The placement of installation symbol modifier fields is the same regardless of frame shape or affiliation.

8-3. Table 8-2 provides a description of each of the installation symbol modifier fields as shown in figure 8-2.

## Chapter 9 Stability Operations And Support Operations Symbols

This chapter establishes a single standard for the development of stability operations and support operations symbols. Joint doctrine uses the term "military operations other than war (MOOTW)" and NATO uses the term "Non-Article 5 Crisis Response Operations (CRO)" for stability operations and support operations. These symbols represent stability operations and support operations activities, locations, and nonmilitary organizations. This chapter includes a wide variety of stability operations and support operations symbols. Avoid using any symbols, or combinations and modifications of symbols, different from those in this manual. If, after searching doctrinal symbols and modifiers, a new symbol must be created, explain it in an accompanying legend. Computer-generated systems may have difficulty in passing nonstandard symbols.

## Composition Of Stability Operations And Support Operations Symbols

9-1. A stability operations and support operations symbol is composed of a frame, color (fill), stability operations and support operations symbol (icon), and text or graphic modifiers (see figure 9-1). See table 9-1, page 9-2, for the steps used to build stability operations and support operations symbols.

| Step #                                                                        |
|-------------------------------------------------------------------------------|
| Friendly Psychological Operations                                             |
| Step 1.                                                                       |
| First, choose the frame that matches the                                      |
| affiliation of the stability operations and                                   |
| support operations organization or                                            |
| situation (friendly, hostile, neutral). Then                                  |
| choose the basic stability operations and                                     |
| support operations symbol for field "A"                                       |
| (see figure 9-2; table 9-2, page 9-3; and                                     |
| table 9-3, page 9-6). In this example, the                                    |
| affiliation is friendly and the situation is                                  |
| "psychological operations." (See the                                          |
| following stability operations and support                                    |
| operations land frame shapes and                                              |
| affiliations.)                                                                |
| Stability Operations and Support Operations Land Frame Shapes and Affiliation |
|                                                                               |
| Steps 2-4.                                                                    |
| Choose the second/third/fourth                                                |
| functional symbol modifier that further                                       |
| explains the capability of that stability                                     |
| operations and support operations                                             |
| symbol, modifying field "A." In this                                          |
| example, the secondary function                                               |
| symbol modifier is "person-to-person                                          |
| psychological operations" (see table 9-                                       |
| 3, page 9-6).                                                                 |
| Friendly Person-to-Person Psychological                                       |
| Operations                                                                    |
| Step 5.                                                                       |
| Choose text modifiers as necessary to                                         |
| provide further amplifying information.                                       |
| In this example, the text modifier is the                                     |
| location (field "Y") of where the person-                                     |
| to-person psychological operations are                                        |
| being conducted.                                                              |

## Appendix A Tactical Mission Graphics

Tactical mission graphics are used in course-of-action sketches, synchronization matrixes, and maneuver sketches. They do not replace any part of the operation order. The graphics in this appendix are representations of many of the tactical mission tasks. Not all tactical mission tasks have an associated graphic. Tactical mission graphics should be scaled to fit the map scale and size of unit for which they are used. Where practical, the tactical mission graphic should connect with the decision graphic at the center of the left or right side of the symbol or at the center of the bottom of the symbol, depending on the orientation of the graphics. See figure A-1, page A-7, for an example of decision graphics and tactical mission graphics used together. For information on building decision graphics, see appendix D. In the examples shown in table A-1, the hostile force would be located to the right of the symbol. However, these graphics can be oriented in any direction relative to the position of hostile forces.

Note: Those tactical mission graphics that are defined in the terminology section of this manual are identified with a page number where the definition can be found. A detailed explanation of each tactical mission task can be found in FM 3-90.

## Appendix D Military Decisionmaking Process Graphics

The tenets of Army operations are initiative, depth, agility, synchronization, and versatility. If commanders and staffs are to adhere to these tenets, they need information in a format that assists them to adapt quickly to the changing factors of METT-TC. The military symbols portrayed in chapters 4 through 9 are used to plot locations and directions of movement; however, the decisionmaker normally requires additional information for course of action sketches, synchronization matrixes, and maneuver sketches that are not readily available by studying a current situation map. The battlefield envisioned by our current doctrine requires rapid and frequent changes in task organization of units to seize or retain or take the initiative and move optimally task-organized forces to the critical point on the battlefield. Military decisionmaking process graphics are a tool for portraying the necessary information.

## Status And Assessment Charts

D-1. Commanders require two general categories of information when analyzing the situation map: the status of equipment and personnel, and the composition of the task-organized forces. Two common methods for displaying information and identifying status are the bar chart and the gumball chart.

FM 6-0 provides information on the use of status and assessment charts.

## Bar Chart

D-2. The bar chart is used to display quantities or percentages. Its major advantage is that it provides a simple method for comparing status indicators to each other and to a set, standard reference point. Bar charts also give the staff flexibility to display and relate various types and combinations of information for the commander. Figure D-1 shows an example of a bar chart.

## Gumball Chart

D-3. The gumball chart provides a clear picture of the status of designated elements using a color code established in the unit standing operating procedures. The chart assists the commander to quickly assess the status of critical elements and assists the staff to focus on problem areas. Choose a color code consistent throughout all echelons of the command.

D-4. The following is a commonly used color code:
-
Green indicates that the unit is at 85 percent or greater strength (combat capable).
-
Amber indicates that the unit is at 70 to 84 percent strength (combat capable with minor deficiencies).
-
Red indicates that the unit is at 50 to 69 percent strength (combat ineffective, unit has major losses or deficiencies).
-
Black indicates that the unit is at less than 50 percent strength (requires reconstitution before next mission).
-
White indicates not applicable or no information available.
D-5. See figure D-2 for an example of a gumball status chart.

## Combat Effectiveness Graphics

D-6. Situation reports (SITREPs) focus on the collection of information about the ability of subordinate units to perform their mission. Appropriate staff elements use various formats to report factors such as the status of fuel, ammunition, vehicle availability, and personnel. The commander, however, provides the net assessment of his unit's ability to perform the mission. This assessment can be expressed using decision graphics as shown in figure D-3.

D-7. The center column of figure D-3 visually depicts the overall combat rating of the unit, and the right column specifies the status of selected items of interest. The standing operating procedures (SOP) will specify the items of interest to be reported higher. The subordinate commander may add to this list for his internal reporting and tracking. The four items shown in the right column are ammunition, weapons, POL, and personnel.

## Task Organization Composition Graphics

D-8. The resources available to the ground maneuver commander are provided as a detailed listing in the task organization portion of the operation order. This detailed listing may be later modified by fragmentary and warning orders. The headquarters and individual units of the task organization may be portrayed graphically by using multiple unit symbols as shown in chapter 5 of this manual. These symbols provide a rapid and easily understood means through situation maps, overlays, and annotated aerial photographs to express an operation plan, concept, or friendly or hostile (enemy) situation. However, they do not provide decisionmakers with a quick and easy method of portraying information relating to task organization composition. D-9. Figure D-4 shows a task force organized around the headquarters of the 2d Battalion, 2d Infantry Regiment (mechanized), of the 1st Brigade, 1st Infantry Division (mechanized) using a unit symbol. The task force unit symbol (figure D-4) shows the basic unit, but does not show how the unit is organized. While the overall combat effectiveness of the unit can be displayed using

## _______________________________________________Military Decisionmaking Process Graphics

the "K" field, more detailed information on combat effectiveness can not be displayed. Although this data may be available through other charts, reports, and briefings, its impact can be lost if the decisionmaker is required to go to different documents. D-10. Using the task organization branch or function symbols, figure D-5 shows TF 2-2 as a task organization composition graphic. It provides the details of how the task force is organized. Table D-1 shows examples of task organization branch or function symbols for use in building decision graphics. (Task organization unit graphics are never displayed in conjunction with unit symbols as shown in figure D-4.) In figure D-5, Task Force 2-2 Mechanized Infantry is organized with two mechanized infantry companies, one armor company, one engineer company, and one reduced antitank company. D-11. The task organization composition graphic is built using a rectangular frame. On the top and centered in the middle of the rectangular frame is the echelon graphic symbol and task force symbol (if required). Inside the frame on the top line is the unique designation of the organization being displayed. If any unit is not one echelon lower than the designated unit on line one, then the echelon indicator is used above the task organization unit graphic (see figure D-7 on page D-8.). For a unit that is reduced, reinforced, or reduced and reinforced, use the appropriate symbol (see figure D-5).

_______________________________________________Military Decisionmaking Process Graphics

## Decision Graphics

D-12. Combat effectiveness graphics and task organization composition graphics can be combined to form decision graphics. Examples of decision graphics at the company/team, battalion/task force, and brigade levels are displayed in figure D-6, page D-8; figure D-7, page D-8, and figure D-8, page D-9. Using the color coding system for gumball charts as described in paragraphs D-3 and D-4, green, amber, red, or black can be used for the fill colors or outlines of the task organization unit graphics to show the combat effectiveness status of the subordinate units. Decision graphics can be combined with mission graphics (appendix A) for use in course of action sketches, synchronization matrixes, and maneuver sketches. See figure A-1, page A-7, for an example of decision graphics and tactical mission graphics used together. FM 101-5 provides information on the use of decision graphics and tactical mission graphics. D-13. In figure D-6, Team A, 1st Battalion, 72d Armor is organized with two mechanized infantry platoons and one armor platoon. It has "some problems"
performing its mission because of weapons systems.
D-14. In figure D-7, Task Force 1-72 Armor is organized with two mechanized infantry companies, two armor companies, and an air defense platoon. It has "major problems" performing its mission because of personnel and weapons systems.
