This publication compiles Department of Defense Military Standard (MIL-STD) 2525E approved military symbols applicable to land operations for use in U.S. Army doctrinal publications, situation maps, overlays, and annotated aerial photographs for all types of military operation. MIL-STD 2525E is the single standard for developing and depicting computer-generated military symbols for use in command and control systems. FM 1-02.2 is the proponent for hand drawn alternate symbols, course of action sketch symbols applicable to U.S. Army doctrine, and approved for use military symbols that are not currently included in MIL-STD 2525E due to difference in revision timeline. This publication is the standard for properly constructing land operations associated military symbols for communicating instructions to subordinate units, commanders, and staffs from company through corps echelons. This publication is augmented by FM 1-02.1, Operational Terms, and the Army Dictionary online. Changes to military symbols occur more frequently than traditional publication media can be updated. The terminology and military symbol database, known as the Army Dictionary, is updated monthly to reflect the latest editions of Army publications. (To access the database, go to https://jdeis.js.mil/jdeis/index.jsp?pindex=207, and log in with a common access card.) This database is an official DOD website, maintained by the Combined Arms Doctrine Directorate in collaboration with the Joint Staff Directorate for Joint Force Development. The site is part of the Joint Doctrine, Education, and Training Electronic Information System. It includes all Army doctrinal terms and all military symbols in MIL-STD 2525E, including air, land, maritime, space, activities, and control measures. FM 1-02.2 is organized in seven chapters: Chapter 1 introduces military symbol fundamentals. Chapters 2 through 4 provide symbols for units, organizations, equipment, installations, and activities. Chapter 5 introduces control measure and operation symbols. Chapter 6 discusses tactical mission tasks. Chapter 7 discusses the course of action sketch. These chapters provide detailed requirements for composing and constructing military symbols. The rules for building a set of military symbols allow enough flexibility for users to create any symbol to meet their operational needs. All military symbols construct standards are governed by MIL-STD 2525E, and this publication serves as the compendium of land related military symbols used in U.S. Army doctrine and training manuals. The introductory table on page X provides a listing of new and modified military symbol changes published in this manual. Table introduction-1.

This chapter discusses the MIL-STD 2525E military symbol construct standards for framed and unframed symbol standard identity, physical domain, color usage, and the placement of Main function symbols, modifiers, and amplifiers. Military symbols are logograms that represent words or terms used to depict abstract graphic representations of a unit, equipment, installation, activity, control measure, or tactical mission task relevant to military operations. These symbols are available for use in course of action sketches, visualizing operation orders, planning, maps, overlays, and command and control system displays to represent a current common operational picture. FRAMED SYMBOLS 1-1. Framed symbols allow the depiction of units, equipment, installations, and activities by using a combination of main function, modifiers, amplifiers, and color (optional) to complete the symbol build. The frame is the border of the symbol and serves as the base to which other symbol components are added, and it indicates the standard identity, physical domain, and status of the object being represented. Framed symbols may use standard identity colors to enhance depiction or may be black and white if the display does not support color. (See table 1-4 on page 5 for a listing of standard identity colors.) S TANDARD I DENTITY 1-2. The framed shape design identifies a symbol’s standard identity. The standard identity frame shape categories are friend, assumed friend, hostile, neutral, and unknown. Table 1-1 depicts the standard identity frame shapes categorized by physical domains. P HYSICAL D OMAIN 1-3. The physical domain defines the primary mission area above the earth’s surface (in the air domain or space domain), on the earth’s surface (in the land domain or maritime domain), or below the earth’s surface (in the subsurface domain). Frame shapes differ by surface (land and sea), sea subsurface, air, and space physical domains. Table 1-1 lists and depicts the frame shapes usage for each of these physical domains by land unit, installation, activity, land and sea surface equipment, air equipment (in flight), space equipment (in orbit), and sea subsurface equipment. 1-4. Frame shape symbol use is dependent on the object’s current physical domain. An aircraft, regardless of Service ownership, can be depicted in either the air domain (in flight) or land domain (on the ground), while aviation units are depicted as land units and facilities as land installations. The exception is surface equipment (land and sea) frames that do not change between land and maritime physical domains. An example is an amphibious vehicle that uses the same frame shape regardless of current physical domain because it can operate in both land and maritime domains. M ODIFIER S YMBOL FOR U NITS, E QUIPMENT, I NSTALLATIONS, OR A CTIVITIES 1-8. A modifier provides additional capability information. Modifiers conform to the placement diagram and are placed in the sector 1 or 2 modifier areas. Some modifiers are interchangeable (multiple usage) and may be used as either a sector 1 or 2 modifier. This publication defines various types of modifiers and indicates their placement in relation to the main function. S TANDARD I DENTITY C OLORS 1-9. Standard identity colors are used as the fill areas for framed symbols. Line colors are used for unframed and framed symbols. Additionally— • Unframed symbols require color as the standard identity indicator if text amplifiers are not used to categorize the symbol. • Fill and line color are optional for framed symbols because the frame design provides the standard identity, and color is only a redundant identity indicator used to enhance the framed symbol. The framed symbol fill is normally white or transparent when color is not used in the depiction. Table 1-4 provides the approved standard identity color variants for military symbol construct fill and line colors.

This chapter discusses symbols for units and organizations. UNIT AND ORGANIZATION SYMBOLS 2-1. A unit is any military element whose structure is prescribed by a competent authority (JP 3-33). This section includes the lists of amplifiers, main functions, and modifiers for constructing unit and organization symbols. UNIT AND ORGANIZATION FRAME SHAPES 2-2. Unit and organization frame shapes are used to identify friend, enemy, neutral, or unknown affiliated units. Table 2-1 provides the standard identity frame shapes for units and organizations. The frame-shape build guidelines for main function, modifier and amplifier placement is provided in paragraph 2-3. 2-6. Task organization indicator amplifier (Field D). This amplifier is used with a battalion task force or company team. A battalion task force is a maneuver battalion-size unit consisting of a battalion headquarters, at least one assigned company-size element, and at least one attached company-size element from another maneuver or support unit (functional or multifunctional). A company team is a combined arms organization formed by attaching one or more nonorganic armor, mechanized, infantry, Stryker infantry, or infantry platoons to a tank, mechanized, infantry, Stryker, or infantry company, either in exchange for, or in addition to, its organic platoons. (See ADP 3-90 for more information on company teams.) Figure 2-5 on page 19 provides the template for a tsk organization amplifier, and table 2-4 on page 19 shows the task organization amplifier and construct examples. 2-9. Command post using staff comments amplifier (Field G). A command post is a headquarters or a portion there of, organized for the exercise of command and control (FM 6-0). The headquarters staff indicator (Field S) is always used in conjunction with the command post and command group amplifiers. Figure 2-9 shows the template for the command post using amplifier Field G, and table 2-6 provides amplifier usage examples. 2-11. A unit designation construct uses the solidus (/) between echelons to identify a continuous hierarchy of command. Figure 2-11 provides an example of the solidus being used in a military symbol construct for 1st Platoon, 51st Transportation Company, 181st Transportation Battalion. 2-12. Hyphens (-) are only used to depict combat units that maintain regimental affiliations but have no regimental headquarters and are organized as part of a brigade. The use of the hyphen in the unit designation construct retains the units’ traditional regimental affiliation and avoids confusing units that do not have a regimental commander from regiments which have remained organized with a regimental headquarters. Figure 2-12 provides an example of a hyphen being used in a military symbol construct for A Battery, 6th Battalion, 37th Field Artillery Regiment. 2-13. Higher echelon command using higher information amplifier (Field M). This additional text amplifier provides a unit symbol a space for the title or number of the higher echelon command. (Roman numerals are used to designate corps.) Figure 2-13 shows the template, and figure 2-14 provides a construct example for A Battery, 6th Battalion, 37th Field Artillery Regiment, 2nd Infantry Division, III Corps. 2-14. Direction of movement amplifier (Field Q). The direction of movement amplifier is an arrow or staff identifying the direction of movement or intended movement of an object. For unit and equipment symbols, the amplifier is an angled arrow extending downward from the bottom center of the frame or symbol and pointing in the direction of movement. Figure 2-15 on page 25 shows the template, and figure 2-16 on page 25 is a direction of movement usage construct example of an enemy guerrilla infantry company. 2-15. Combat effectiveness amplifiers (Field K). This amplifier field provides the ability to display the level of combat effectiveness of a unit. Figure 2-17 shows the template for the combat effectiveness amplifier. Combat effectiveness is the ability of a unit to perform its mission, and this amplifier uses the following rating factors for ammunition, personnel, fuel status, and weapons systems: • Fully operational (FO) – (85 percent or greater) • Substantially operational (SO) – (70 to 84 percent) • Marginally operational (MO) – 50 to 69 percent) • Not operational (NO) – (less than 50 percent) • Unknown (UNK) 2-16. Offset location indicator amplifier (Field S). To indicate a precise location or reduce the clutter of headquarters and non-headquarters unit symbols. The offset location line has no restriction in length. There are two types of offset location indicators: • Headquarters offset location indicator. Figure 2-18 shows usage examples of the headquarters offset location indicator for friendly and hostile units. The staff extends vertical from the bottom left-hand corner to the headquarters location point. 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 echelons in descending order. • Non-headquarters offset location indicator. Figure 2-19 on page 27 shows an example of how to use the offset friend and hostile units that are not headquarters. For a single unit, the field moves to the bottom center of the frame and the line extends to the exact location point. For grouping of non-headquarters unit symbols, use a bracket with a line extending from the left side of the bracket and ending at the exact location point. 2-17. Offset location indicator extension line amplifier (Field S2). Field S2 is a line that extends from the end of the offset location indicator amplifier “Field S” to the desired location point. This offset location extension line has no length or direction restriction. Figure 2-20 shows examples of how to use the offset location indicator for friendly and hostile headquarters units. Figure 2-21 shows an example of how to use the offset extension line for non-headquarters units. MAIN FUNCTION SYMBOLS FOR UNITS 2-18. Most Army Main function symbols for units were determined by table of organization and equipment and modified table of organization and equipment descriptions in the Force Management System of the Army Force Management Support Agency. This section also includes a limited number of North Atlantic Treaty Organization (NATONATONorth Atlantic Treaty Organization) and civil authority main function symbols. 2-19. Main function symbol (Field A). The Main function symbol is located in the center sector of the octagon, and it reflects the main function of the symbol. (See table 1-5 on page 8 for the construction process for framed symbols.) Table 2-7, on pages 28 through 43, shows the Main function symbols for units.

This chapter discusses Main function symbols and sector 1 and 2 modifiers used with activities and installation frames. ACTIVITY FRAME SHAPES 3-1. This frame is used to identify friendly, enemy, or criminal actions that can reveal civic, ethnic, religious, social, or other grouping activities in an area of interest or operation that may affect unified land operations. The frame shape follows the construct guidelines in chapter 1, main and modifier symbols, the activities frame shapes for standard identities in table 3-1, and amplifier placement locations in figure 3-1. 3-4. Activity direction of movement amplifier (Field Q). The activity direction of movement amplifier is an arrow extending from the center of the frame or Main function symbol. The arrow extends in the direction of movement or intended movement of activity symbol. Figure 3-3 is an example of the usage construct. 3-5. Activity offset location indicator amplifier (Field S2). The offset location amplifier for activities is placed differently from units and installations. Field S2 is located at the center of the bottom of the activity frame and the offset location indicator line protrudes from this point (without an arrow) to the desired location. The line may be extended or bent as needed. Figure 3-4 is an example of the usage construct of a friendly organized group meeting activity. INSTALLATION FRAME SHAPES 3-6. This frame shape is used to identify friendly military, civilian, or enemy installations, facilities, campuses, terminals, depots, caches, and specific buildings in an area of interest or operation that supports or may support a common interest during unified land operations. The frame shape follows the construct guidelines in chapter 1 and the activities frame shapes for standard identities in table 3-3.

This chapter discusses Main function symbols, sector 1 modifiers, and mobility indicator amplifiers for equipment. Equipment is nonexpendable items needed to outfit or equip an individual or organization. This section includes the lists of main and modifier symbols and amplifiers for building land equipment symbols. FRAMED AND UNFRAMED EQUIPMENT SYMBOLS 4-1. The equipment symbol construct standard permits the option to depict the symbol with frame or unframed. As discussed in chapter 1, the frame shape is what indicates the standard identity (friendly, enemy, neutral, and unknown) of a symbol. The unframed equipment symbol constructs must use colors (including blue, red, green, and yellow) in order to indicate the standard identity depiction of friendly, enemy, neutral, or unknown items. (See paragraph 1-9 for more information on standard identity colors.) EQUIPMENT SYMBOL FRAME SHAPES 4-2. The symbol frame shape is used to identify friendly, enemy, neutral, and unknown equipment affiliation in or supporting an area of interest or operations. Table 4-1 provides the standard identity frame shapes for units and organizations. The frame shape construct guidelines for main and modifier symbols and amplifier placement locations are provided in paragraph 4-4. mobility vehicle with medium gun system 4-5. Engagement bar amplifier (Field AO). The engagement amplifier bar may be used to designate engagements and to indicate targets. Both may be done in conjunction where depicted targets contain engagement information. The engagement bar may contain information on 1) remote or local engagement; 2) stage of the engagement (for example, assign, cover, engage, hold fire, cease fire, cease engage, break engagement, or missile in flight); and 3) type of weapon assignment (for example, missile, gun, or torpedo). Engagement bars use four colors: red, white, and orange for hostile targets, and blue for friendly participating. (See table 4-3.) Figure 4-3 depicts an example of a friendly self-propelled (tracked) long range surface to air missile launcher engaging an enemy attack rotary aircraft. (See MIL-STD 2525E for more detailed technical information concerning expanded usage of the engagement bar.) launcher engaging an enemy attack rotary aircraft 4-6. Mobility (transportation) mode indicator (Field R). The mobility (transportation) mode indicator is only used to depict the mode of transport of equipment. For example, a symbol for an armored self-propelled howitzer transported by train would include a railway mobility mode indicator in Field R (see figure 4-4.) Table 4-4 on page 113 provides a list of mobility (transportation) mode indicators with construct examples of the transporting of a howitzer. mobility vehicle with medium gun system 4-8. Operational condition amplifiers (Field AL). This field allows the display of the level of operational condition of the equipment. Table 4-5 on page 115 shows operational condition amplifiers and construct examples.

This chapter discusses military symbols used to control, coordinate, and identify military and related actions in the conduct of land operations. FUNDAMENTALS 5-1. Control Measures Symbols. A control measure is the means of regulating forces or warfighting functions (ADP 6-0). Control measure symbols use a combination of military symbols constructs to depict offense and defense operational capabilities and to de-conflict areas, space, and time to regulate forces or warfighting functions. Control measures provide the means to visualize and understand current combat capabilities when combined with other symbols and amplifiers to depict operational information on maps and displays. Figure 5-1 provides an example of the use of a unit symbol construct with a control measure to depict a controlled offensive maneuver. 5-2. Operations Planning Symbols. Operation planning symbols identify planned actions, events, affects, built-up areas (building, fortified area, obstacles), and gap crossings. Some operation planning symbols are related to offensive and defensive operations but are not control measures. They may be used to depict planned actions conducted during offense and defense operations to enhance the operational picture of an operation. STANDARD IDENTITY COLORING 5-3. Friendly graphic control measures use black or blue when drawn manually or on a color computer-generated display. Hostile graphic control measures use red. If red is not available, they are drawn in black with the abbreviation “ENY” placed on the graphic in at least two places. Obstacles as shown in this chapter are drawn using green. If green is not available, obstacles should be drawn using black. The hatching for CBRNCBRNChemical, biological, radiological, and nuclear contaminated areas uses the color yellow. ACRONYMS AND ABBREVIATIONS USAGE 5-4. The acronyms and abbreviations in this chapter are considered symbols that are part of the military symbol construct for use with Army control measure symbols. No acronyms or abbreviations other than those provided in this publication may be used. When acronyms or abbreviations are approved for use with military symbols, they become part of the military symbol lexicon. LABELING CONTROL MEASURES 5-5. Symbol makers make all text labeling in upper case letters. The reader should be able to read the labels for all text labels of modifier or amplifier fields for control measure symbols when the bottom of the overlay is closest to the reader. Labeling written on an angle should be readable to viewers horizontally. 5-6. Status refers to whether a control measure exists at the location identified (status is “present”) or will in the future reside at that location (status is “planned” or “suspected”). In general, linear control measures shall be a solid line when indicating present status and a dashed line when indicating suspected or planned status, as depicted in table 5-1. There are certain control measures such as counterattack which are drawn in the “present” status with dashed lines. DIRECTION OF MOVEMENT INDICATOR (FIELD Q) 5-11. The direction of movement indicator is an arrow identifying the direction of movement of events. The arrow extends downward from the center of the symbol and points in the direction of movement. The indicator is positioned as shown in figure 5-3 on page 151 and Field Q is defined in table 5-1 on page 148. OFFSET LOCATION INDICATOR (FIELD S) 5-12. The offset location indicator is used when placing an object away from its actual location. The indicator is a line extending downward from an appropriate anchor point on a symbol. This amplifier permits including the actual location in latitude and longitude between the anchor point of the symbol and the line extending downward. The indicator is positioned as shown in figure 5-4 and Field S is defined in table 5-1 on page 148. ADDITIONAL INFORMATION AMPLIFIER (FIELD H) 5-13. The additional information amplifier field is used to add content that is implementation specific, provided it does not exceed the allowed 20 maximum number of characters. This amplifier is positioned differently based on the symbol used. Figure 5-5 provides 2 different position variation constructs for this field. BOUNDARIES 5-14. A boundary is a line that delineates surface areas for the purpose of facilitating coordination and deconfliction of operations between adjacent units, formations, or areas (JP 3-0). Figure 5-6 provides a boundary composition template that includes orientation of optional field amplifier labels for horizontal (east—west) and vertical (north—south) boundaries. (See table 5-3 on pages 153 through 154 for depictions of boundary control measures. The following are optional amplifiers that may be used with this control measure construct: • Country code Field AS to identify the units’ three-letter geographical entity country code. • Echelon indication Field B to identify the boundary echelon. • Hostile (enemy) Field N to identify enemy boundaries. • Unique identifier Field T to identify designations of adjacent units. 5-16. Table 5-4 on pages 155 through 159, lists area control measure Main function symbols that follow the specific format as shown in figure 5-7. symbols 5-21. Point control measure. Table 5-6 on page 164 through 176 lists point control measure Main function symbols that follow figure 5-8 template construct formats. A properly designated commander uses these points to exercise authority and direction over assigned and attached forces to the accomplishment of the mission.

This chapter provides symbols for tactical mission tasks. TACTICAL MISSION TASKS DEFINED 6-1. A task is a clearly defined and measurable activity accomplished by individuals or organizations. A tactical mission task is the specific activity a unit performs while executing a tactical operation or form of maneuver. (FM 3-90). The tactical mission tasks describe the results or effects commanders want to achieve. SYMBOLS FOR TACTICAL MISSION TASKS 6-2. Table 6-1 on pages 239 through 243 shows the tactical mission tasks that have symbols. Not all tactical mission tasks have symbols. Tactical mission task symbols can be used with unit symbols, but they do not have modifiers. Tactical mission task symbols are used in course of action sketches, synchronization matrices, and maneuver sketches. They do not replace any part of the operation order. Tactical mission task symbols are sized to accommodate the scale of the display or map being used.

This chapter discusses the purpose and makeup of a course of action sketch. PURPOSE OF COURSE OF ACTION SKETCH 7-1. A course of action is a scheme developed to accomplish a mission (JP 5-0). Developing, analyzing, and deciding on a course of action for execution is central to planning. Part of course of action development is to produce a course of action statement and sketch. The staff prepares a course of action statement and supporting sketch for each course of action under consideration. A course of action statement clearly describes the array of forces and the sequence of tasks the unit will conduct to accomplish the mission. The statement should be a brief expression of how the combined arms concept will be conducted. The course of action sketch is the graphic portrayal of the course of action statement. The sketch provides a picture of the movement and maneuver aspects of the concept, including positioning of forces. (See FM 6-0 for a detailed discussion of the military decision-making process, including course of action development.) MAKEUP OF COURSE OF ACTION SKETCH 7-2. The course of action sketch provides a picture of the movement and maneuver aspects of the concept, including the positioning of forces. The course of action sketch becomes the basis for the operation overlay. At a minimum, the course of action sketch includes the array of generic forces and control measures, including— • Unit and subordinate unit boundaries. • Unit movement formations (but not subordinate unit formations). • Reconnaissance and security graphics. • Ground and air axes of advance. • Assembly areas, battle positions, strong points, engagement areas, and objectives. • Obstacle control measures and tactical mission graphics. • Fire support coordination and airspace coordinating measures. • Main effort. • Location of command posts and critical communication nodes. • Enemy locations, known or template. • Population concentrations. 7-3. Most symbols for use on the course of action sketch are shown in chapters 2 through 7. However, the unit symbols do not provide decision makers with a quick and easy method of portraying detailed information relating to task organization, composition, or combat effectiveness. Task organization composition symbols portray detailed information for course of action sketches. TASK ORGANIZATION COMPOSITION SYMBOLS 7-4. Part of course of action development includes determining relative combat power and arraying forces to accomplish the primary tasks envisioned during action. After arraying forces, planners then group these forces underneath a generic headquarters representing the initial task organization. The initial task organization for each generic unit is portrayed in a task organization composition symbol. 7-5. Task organization composition symbols are constructed using a rectangular frame, main and modifier symbols, and amplifiers. Figure 7-1 depicts Main function symbol and amplifier fields. The Main function symbols and amplifiers have specific field placement guidelines that follow current military symbol standards. Field A is used to depict subordinate unit symbols using the task organization symbols in table 7-1. While there are four symbols shown in table 7-1, there is no limitation as to the number of symbols in a row or number of rows. If needed, the first line of field A can be reserved to identify only those units that have been reinforced (attached) “(+)”, reduced (detached) “(-)”, or reinforced and reduced (attached and detached) “(±)” and for units that are one or more echelons lower than the other designated units. Field B is used to identify the echelon level of the headquarters. See chapter 2, table 2-3 on page 15 for echelon amplifiers. Field D denotes task force. See chapter 2, table 2-4 on page 19. Field H is available for including a generic alphanumeric designation of the organization. Field K is available for including the combat effectiveness using the symbols in table 7-2 on page 249. T ASK O RGANIZATION M AIN AND M ODIFIER S YMBOLS 7-6. In all cases, task organization symbols are the same as unit main and modifier symbols and amplifiers. Table 7-1 on page 247 shows the most commonly used main and modifier symbols in their appropriate configurations. This page intentionally left blank.
