DESIGNATION BY ARM ·oR .B'RA.NCH OF SERVICE Rarely will modern ground ·warfare be conducted solely by a single arm or branch of seTVice. Military units, representing various branches 'Of service, work closely together under a single command. Traditionally, however, armies have .been .divided into arms and branches of service. Although today's battlefield requirements demand the combined effort of all types of troops, the traditional arm or branch symbol plays an important role in developing proper symbols for various military groupings. These branch of service -symbols are shown below.

DESIGNATION BY DUTY PERFORMED F1·equently, it is more purposeful to denote the duties performed by a unit rather than its arm or branch of service. Symbols have, therefore, been adopted to represent specific duties, functions, or equipment. Many of these symbols have been standardized and are normally used in combination with other symbols.

COMBINING BRANCH OF SERVICE AND DUTY PERFORMED SYMBOLS ~· Combat operations usually call for military organizations specially equipp.ed and trained· to accomplish a specific tactical mission. To pictorially represent these specialized military organizations, a combination of symbols may be placed within the unit or installation symb()l, as long as the symbol r~mains clear and easily understood. Examples of symbol combinations are shown below.

BASIC WEAPON SYMBOLS a. Symbols are also ~1sed to indicate the type and location of a weapon or group of weapons. When a weapon symbol appears on a map or overlay, the base of the shaft indicates the location of the weapon. b. To show the approximate size of a particular weapon, the procedure is as fo1Iows: (1) Select the appropriate weapon symbol. Examples: (~asic infantry weapon) (Basic artillery we~pon) (2) One (for medium) or two (for heavy) horizontal bars are added to denote approximate size. If no horizontal bar is shown, the light category is represented. Examples: 1' (Light automatic weapon) (Medium artillery gun) c. If a weapon has a high trajectory, a 0 is placed at the base of the shaft. Example: (Mediulll mortar) d. If the weapon is a flat trajectory, antitank weapon, a 1\ is placed at the base of the shaft. Example: (Light antitank gun) e. If the weapon is primarily for air defense; a. C is placed at the base of the shaft. Example: (Heavy air defense gun) f. If the weapon is a rocket projector or launcher, a A, is placed at the head 9f the shaft. ~ Example: lj r (Light artillery rocket launcher) AGO 9142A FM 21-30 g. If a weapon is also a tracked, self-propelled vehicle, a 0 is placed below the weapon symbol. Example: ~ <> (A tracked, self-propelled medium hovvitzer) h. Weapon symbols and missile launching sites are shown below.

GROUPING OF WEAPONS Groupings of weapons or multiple barrels may be indicated by writing the number of weapons to the left of the symbol. Examples: (Four medium mortars) (Four light anti-aircraft ,guns or one four-barrel light anti-aircraft gun) 2-12. ALTERNATE METHOD OF ·siZE iNDICATION Another method of indicating the size of a weapon is to write the caliber of the weap.on to the right of the symbol. Examples: (81-mm mortar) (105-mm howitzer) AGO 9142A FM 21-30 2-13. ARMORED VEHICLE SYMBOLS Symbols have also been adapted to represent armored combat vehicles.

Symbols fo1' vehicles other than those shown in paragraph 2-13 are made by combining two types of symbols. One symbol denotes the kind of body; the other, the means of mobility. (1) Body types. (a.) Personnel and/or cargo carrying (b) Operational unarmored AGO 9142A 2-15 FM 21-30 (c) Operational armored • (d) Amphibious armored (e) Amphibious (cargo) (f) Engine/locomotive (2) Means of mobility. (a) Tracked or half-tracked (b) Self-prop~lled (tracked) (c) Self-propelled (wheeled) ( cl) Wheeled 0 0 (e) Wheeled cross-country 0 0 0 {f) Railway 00 00 ( ) (g) Sledge (towed) (h) Over-snow (prime mover) \__\__ (i) Animal (i) Barge or boat 1\1\ v 2-.-16 AGO lll42A • FM 21-30 b. Branch or administrative symbols may be placed ins.ide the body type to indicate the vehicle load or usage. Further details, such. as capacity of vehicle, may be indicated below the symbol. Examples: (1) tj A five ton cargo wheeled vehicle 5 TON (2) w An ambulance boat (3) M A cargo carrying sledge (supplies/rations) (4) (~ A tracked amphibious vehicle, (cargo/personilel) 2-15. COMBINING EQUIPMENT AND UNIT SYMBOLS If it is desired to indicate the principal weapon or piece of equipment with which a military unit is equipped,·the appropriate·symbol is piaced directly under the unit symbol. Examples: • I 1105 (Artillery battery with 105min howitzers) b. ~ w (Chemical smoke generator platoon) AGO 1114& 2-l'l FM 21-30 Section IV. UNIT DESIGNATIONS • 2-16. PARENT UNITS A parent unit has a title or numerical designation assigned to no other similarly organized and equipped unit. All military units are either directly related through command echelons to a parent unit or ~re, in themselves, parent units. The level of command designated as the parent unit is variable.•To determine the parent unit for any particular organization, consideration must be given to branch of service, organization, nationality, and military tradition. Size, how" ever, is never an indication since parent units vary in composition from a section to an over-all headquarters. A parent unit can be recognized only by its separate and distinctive title or nu;u" her. 2-17. UNIT DESIGNATION AND BASIC SYMBOL a. To indicate a particular unit or installation, the pa1·ent unit designation is placed immediately t(} the 1·ight of the basic unit or installation symbol,· additionally~ the parent unit may be underlined. Higher· echelons of command follow to the right of the parent unit designation. To the left of the basic symbol, subordinate units are shown. Slashes separate command echelons. Only cardinal numerals are used. The arrangement of various combinations of symbols to depict specific units or installation is shown in the ·following diagram: SIZE SUB0 BRANCH OR HIGHER SUBSUB-;iUB SUB · DUTY PARENT UNIT ECHELONS SUB UNIT UNIT UNIT / PERFORMED OF COMMAND ADDITIONAL INFORMATION b. If only one type of unit is assigned to a milita1·y o1·ganization and if the unit is adequately identified by othe1· militaTy symbols, its designation may be omitted. Example: I ~ ~ I~ 150 (Bridge Company, 50th Engineer Battalion) NOTE: Current military organization specifies that only one bridge company will be as'signed as an organic part of the 50th Engineer Battalion. Therefore, since identification of . the Bridge Company is indicated by the bridge symbol within the unit rectangle, further designation is not necessary. 2-18. COMBAT ARMS REGIMENTAL SYSTEM (CARS) Sometimes, parent units are identified by a combination of unit designations. Such a procedure is employed by many units within the U. S. Army and is known as the Combat Arms Regimental System (CARS). Under the CARS system, parent units are designated by both AGO 9142A 2-18. FM 2l...:.SO the battalion (squadron) and traditional regimental numbers. To av~id confusion with different levels of command, both, numerical designations are always written together and separated by a dash, ·r.atker than slashes. Examples: AIZ!l-16 {Company A, 1st Battalion, 16th Infantry.) 16112-68 (12th Battalion,. 68th Armor) (Troop B, 2d Armored Cavalry Squadron, 13th Cavalry) 2-19. ECHELONS OF COMMAND IN COMBINATION WITH DUTY PERFORMED AND SIZE a!. If there is a difference between the arm or branch .of service or duty performed by a military unit and the unit to which it is assigned, the arm.or branch of service or duty performed symbol of the smaller unit is entered in the basic symbol. If desired, the service or duty performed sy~bol of the larger unit maY: be adde.d under the basic symbol. ~ample: I~ ( ) {A signal platoon of a tank unit) b. To show the branch of service or performed duty of one or more echelons in the chain of command, the appropriate symbol may be placed under the echelon. Example: ~ 2_134 . 52:> (Air Cavalry TroQif, 2d Armcn;e'd Cavalry Squadron, 13th Cavalry) AGO 9142A Fl\1 21-30 • c. If it is desired to show the size of any echelon in the chain of command, the appropriate size may be placed over the unit designation. ~ XX Example: ~3-5/9 (3d Battalion, 5th Infantry, 9th Division) d. If an. installation or activity is identified by the unit to which it is assigned and if no fixed unit size is applicable, the size indication is placed over t}?.e command echelon by which the installation is identified. The branch of service or duty performed symbol may be placed under the command echelon if desired. 11 r-;-1xx 2-503 Examples: ~4 (Headquarters, 4th Division Artillery) (Trains, 2d Battalion, 503d Airborne Infantry) 2-20. USE OF ABBREVIAT19NS The use of abbreviations in conjunction with ·military symbols should be avoided whenever possible; however, certain ·units cannot be adequately identified by symbols alone. In the following cases, abbreviations as authorized by AR 820-50 or as shown in this manual ar.e used: a. If a unit is designated by name rather than by number or letter, an abbreviation is normally used. The placement of the abbreviation corresponds to the placement of a numerical or letter designation. Example: SCTY0301 (Security Platoon, 301st Military Police Company) b.. If a unit or installation is designated by letter or number but requires further identification because of a particular duty or purpose. to which no appropriate symbol applies, the additional information in abbreviated form is placed outside and below the basic symbol. AGO 9142A FM 21-30 A lo~c145 Example: FWD SPT (Company A (Forward Support), 45th Maintenance 0 Battalion) c. An over-all headquarters is indicated by placing the abbreviation (short title) ins.ide the basic symbol. Above army group, size symbols are not shown. Example: (Supreme Headquarters, Allied Powers, Europe) d. When no appropriate symbol is provided, the abbreviation of the duty performed may be written inside the ba~ic symbol. Example: e~x COLL (Prisoner of War Collecting Point, 6th Division) 2-21. NATIONAL DESiGNATION . f!,. If necessary to designate the nation to which a unit or installation is assigned, the national distinguishing letters in brackets (parentheses) are written at the extreme right. The national letters pertinent to countries of the North Atlantic Treaty Organization are shown in STANAG 1059, appendix III. XX Example: ~IGIUSl (16th Infantry Division of the United States) b. Units, installations, and activities under national command and not assigned to a force composed of allied nations may be indicated with the symbol 1\ placed over the size indication. AGO 11142A FM 21-30 Example: ~4(US) (4th Infantry Division under the national command of the United States) Section V. U. S. UNIT SYMBOLS 2-22. GENERAL The examples of military symbols in this section are applicable to current and proposedU. S. Army organizations. For reference purposes, each symbol is shown in detail; such detail, however, is not always required. Users are encouraged to consider their own particular needs and to reduce detail to essentials only. Within the division, for example, there is usually no requirement for subordinate units to identify command echelons above the parent unit. As this section is per . tinent to U. S. units only, the use of italics to indicate deviation from NATO-approved symbols has not been followed as in other ~ections of the manual. · 2-23.

SITUATION MAPS AND OVERLAYS 3-1. GENERAL Situation ·maps and overlays provide a rapid and easily understood means by which a commander or staff officer may express an operational plan, concept, or friendly or enemy situation. The combination of unit and weapon symbols with objectives, boundaries,·-routes of march, and other control measures creates an indispensable tool for quickly and accurately portraying battle activity. Standardization of techniques is essential if tactical information is to be relayed without misunderstanding. Guidelines for the pictorial representation of tactical situations are, thereforeJ established in this chapter. 3-2. COLORS a. Colors in conjunction with military symbols denote the following: (1) Blue or Black -Friendly units, :installation, equipment, and activities. (2) Red -Enemy units, installations, equipment, and activities. (3) Yeiiow -Friendly or ·enemy areas of chemical, biological, or radiological contamination. (4) Green -Friendly or enemy man-m!lde obstacles. .b. If other colors are used, a suitable explanation in the margin or legend is given. 3-3. PRESENT AND PROPOSED LOCATIONS Basic unit and installation symbols are drawn with either solid or broken lines. The lower left-hand corner of the symbol indicates the location. a. A solid line ·symbol represents a present or actual location. b. A broken line symbol indicates a future or projected location. XX .----, 1C).1 Examples: ~---' I ' (The location of an infantry battalion) (The projected location of the headquarters of an armored division) TAGO 5926-A FM 21-30 3-4. DATE-TIME GROUPS Dates and times such as the opening of an installation or the expected arrival of a unit in a new location may be written under or insitte the symbol. Date-time gro_ups are used: Examples: .6. XX 0914308 (Present location of an observation post which (Future location of the headquarters of an opened at 1430 hours, Time Zone B, infantry division which is scheduled to openthe 9th of the month) . at 1800 hours, Time Zone A, the lOth of the month). 3-5. PRECISE LOCATIONS To indicate locations more precisely, the following methods are employed: a. Basic symbols other than the headquarters symbol may be placed on a central staff which is extended or bent. as required. The end of the staff indicates exact location. E~mples: p Q ~ b. , Since the headquarters symbol already includes a staff, this staff may be extended or bent as required. The end of the staff extension indicates the exact location of the headquarters. Example: \ c. If a group of units or installations other than headquarters are at one location, the grouping of symbols may be inclosed with a bracket and the exact location indicated with a staff. D Example: 0 ~ d. If several headquarters are at one location, more than one symbol may be placed on a single staff. Example: ,AGO 9U2A • 3-6. TASK FORCES Units forming a temporary grouping may be shown under one command by use of a bracket. FM 21-30 Example: I·•• ·I (An armored battalion task force formed by two tank companies, one mechanized infantry company, one armored engineer platoon, and one aviation section) 3-7. ENEMY FORCES a. "In general, the symbols shown in this manual are adequate for depicting both enemy and foreign units, ·weapons, equipment, and activities. When representing unorthodox units and equipment, the most appropriate symbol contained herein should be selected. b. If only one color is available, enemy symbols are outlined with douple lines. Examples: ~ (Enemy infantry division) (Enemy observation post) c. A question mark used in conjunction with .an enemy symbol :indicates unknown or unconfirmed information. The position of the question mark shows what information is unknown Dr unconfirmed. ~. Examples: [@]] ? ·~ 3'1.1ffll::~ . -.... . (The size of the enemy infantry unit is (All informatffifnconfirmed) a? , '(The unit designation of the enemy tank (The type of enemy regiment is unknown) battalion is unknown) d. On enemy situation ma_ps and ,overlays, a ·da·te-time group indicates "the time the incident or event occurred or the unit or installation was reported. AGO 9142A l"M 21..,30 3-8. FRONT LINES a. Front lines are markedby a series of lines which curve away frQm opposing forces. If op.ly one color is used, enemy front lines are represented by double lines. ~ ~ ~ Example: (\ (\ (\ b. Thinly held or patrolled parts of the lines are marked as a series of dots. If only one color is used, thinly held enemy lines are represented by open dots. The dots do not indicate strength or location of patrols. Example: 0 0 0 0 0 0 0 3-9. OBJECTIVES Objectives and intermediate objectives are inclosed and identified by the abbreviation OBJ and a number, letter, code name, or unit designation. Examples: 3-10. ASSEl\IBLY AREAS (UNDEFENDED AREA) a. Assembly areas are inclosed and the unit symbol is placed in the center. Proposed assembly areas are shown with broken lines. ,..---....... \ 1/ r-.IIII.-, \ Examples: I 1~1 \ l 1\___)13-33/ ' L____J / ,., ...... _-.,.,.. (Assembly Area, Task Force, 3d Tank (Proposed Assembly Area, Task Force, Battalion, 33 Armor) 3d Tank Battalion, 33 Armor) b. If an area is allocated to a group of units, it is often convenient to displace the unit symbols. · Example: AGO 9H2A FM 21-30 3-11. ATTACK POSITIONS Attack positions are inclosed by a line with the abbreviation ATK and unit designation placed in: the center. Example: (Attack position, A Company, 2d Battalion, 18th Infantry) 3-12. DEFENDED AREAS If an area is occupied and defense of the area is prepared, a line including the size symbol of the defending unit incloses the area; the closed side of the symbol is oriented toward the most likely enemy threat.

LATERAL BOUNDARIES Boundaries are marked by a solid line with the-size indication of the unit shown at convenient intervals. The designations of units supplemented by arm or branch and national designation, if necessaq, are placed on either side of the size indication. If a lateral boundary separates units of unequal size, the symbol for the larger is used. Examples: I I ~ 3 DIV I X 2 3 ~ 14ARMD CAV X I I I (Boundary separates 1st Corps (Boundary separates 1st and (Boundary separates 3d and 3d Division) 2d Brigades) Division and 14th Armored Cavalry Regiment) 3-15 REAR BOUNDARIES I~ a rear boundary is shown, the size indication along the boundary corresponds to the smaller unit or, in other words, to the commanded unit and not the commanding unit. Arm or branch and nationality of units are shown when required to prevent confusion. Examples: 43 14 ARMD CAV -----XX------------Ill-----5 CORPS 5 CORPS (Rear boundary separates 43d Division (Rear· boundary separates 14th Armored and 5th Corps) Cavalry Regiment and 5th Corps) 3-16.

INFILTRATION LANE An infiltration .lane is bounded by two solid lines and with the words INFILTRATION LANE and the designation of the infiltrating unit in the center. Example: :AGO 9142A FM 21-30 3-18. AXIS OF ADVANCE a. An axis of advance is normally assigned a code name or unit designation. The open arrow indicates the general route to be followed. A proposed axis of advance is shown in broken lines and fabeled with the time or condition when effective. The point of the arrow touches the objective. Example: b. To differentiate between a ground axis of advance and an ai1· assault axis of advance, a twist is placed in the shaft of the open arrow symbolic of a propeller. Example: (Air Assault Axis of Advance) 3-19. DIRECTION OF ATTACK AND ROUTES OF MARCH --~, A direction of attack arrow is not labeled. Routes of march (advance, withdrawal, main supply, etc.) however, are labeled with their purpose and code name or unit designation. The arrow follows the specific route. Example: ROUTE OF MARCH, 3-52 INF 3-20. CONVOYS a. Convoys of vehicles are represented by an arrow in the direction of movement; the point of arrow indicates the location of the head of the column. Examples: (If the convoy is halted, the arrow is shown facing toward the rear of the column) b. This symbol may be shown with the appropriate vehicle symbol to indicate the type and number of vehicles in the column. Likewise, the date and time may be added.

Inside the segment representing the mushroom head are shown the yield (KT or MT) and the date-time group of the detonation. When not accurately known, the yield is shown between brackets. c. The height of burst is shown in meters along the left side of the stem. If not accurately known, the approximate height should be shown. (HIGH, LOW, SURFACE, UNDERGROUND). d. The direction of the prevailing wind blowing between the ground and the maximum height of the nuclear cloud may be shown by an alTO\V pointing away from ground zero. e. If the mushroom is known to be fallout producing, the stem of the m_ush room is shaded. f. Proposed nuclear detonations may be shown in a similar manner by the use of broken lines. g. The boundaries of areas damaged in various degrees may be.shown by concentric circles with ground zero as center. h. Normal colors for friendly (BLUE or BLACK) and enemy (RED) detonations are used. If only one color is available, enemy nuclear strikes may be indicated by the use of double lines for the mushroom head.
