ABBREVIATIONS

This manual supersedes FM 21-30, August 1, 1939, and Training Circular No. 48, War Department, 1941.

SECTION I

GENERAL

• 1. PURPOSE.—This manual is intended to supply the in formation required by the map reader. Persons engaged in the preparation of maps should be guided by AB 300-15, TM 5-230, and by Bulletin 788, Topographical Instructions of the United States Geological Survey.

• 2. SCOPE.—This manual shows in convenient form the abbreviations and general symbols which have been author ized for military use. The general topographical symbols in section II, the symbols intended for air navigation maps only in section III, and the general abbreviations in section V have been approved by the Federal Board of Maps and Surveys and are prescribed for use on all United States maps. Symbols of a purely military nature prescribed by the War Department are given in section IV and special abbreviations authorized for military use, in section VI. Symbols other than those herein authorized may be used, provided they do not conflict with any authorized symbols and are explained in a suitable legend on the map.

SECTION II GENERAL TOPOGRAPHIC SYMBOLS

• 3. CHARACTERISTICS.—a. Size.—In general, symbols resemble the objects which they represent. The symbols vary in size with the scale of the map. On small-scale maps, symbols are reduced to their most elementary form and do not con form to scale. As the scale is increased, the symbols assume the shape and scaled size of the object represented.

b. Color.—The symbols are shown in appropriate color for a four-color map. When less than four colors are used, the symbols shown in paragraph 4 in the colors not used will be executed in black ink.

c. Lettering.—VERTICAL ROMAN type indicates civil di visions, SLANT ROMAN type (or italic) indicates natural water features, VERTICAL GOTHIC type indicates natural land features, and SLANT GOTHIC type indicates works of man. Lettering, either mechanical or freehand on mili tary maps hastily prepared, may vary considerably from these types. Likewise, marginal data as indicated in para graph 4c will not be nearly as complete on military sketches.• 4. LIST.—a. Works and structures.Canal, ditch, or open aqueduct-.————__J _

SECTION III

SYMBOLS FOR AIR NAVIGATION MAPS

• 5. CHARACTERISTICS.—The conventional signs for use on air navigation maps differ from those used on topographic maps as follows:

a. The features on the ground which are easily discernible from high altitudes are the ones which are emphasized on the air navigation map and the other features are subordinated or entirely omitted. In this way the aviator is provided with a map showing landmarks visible from the air, permitting him to direct his flight by these landmarks.

b. All symbols adopted are larger and more striking to the eye so that the aviator may easily read his map under difficult conditions.B 6. LIST. (Symbols usually reproduced in Red)

SECTION IV MILITARY SYMBOLS

• 7. GENERAL RULES.—a. Color.—When colors are used, mili tary symbols representing objects in territory occupied or controlled by our forces are shown in blue, and those in ter ritory occupied or controlled by the enemy are shown in red. The only exceptions are the following:

(1) Symbols for areas to be covered by friendly fire or gas, although generally located in enemy territory, are executed in blue.

(2) Symbols for gassed areas, wherever located, are always executed in red.

b. Unit designations.—The positions of various letters, numbers, or abbreviations designating definite units with respect to the symbol representing the type of unit are as follows:

(1) Serial numbers of armies and corps are placed within the symbol for troop units when considered collectively. Army is shown by number spelled out. Corps is shown by roman numerals. Serial numbers of divisions, brigades, regi ments, separate battalions, separate companies, or similar separate units are placed on the right, using arable numerals.

When separate units are designated in this manner, the number of the unit will be followed by an abbreviated ex planation showing the size of the unit thus designated.

20


(2) Numbers designating battalions in a regiment are shown on the left, using arable numerals.

(3) Letters designating companies, troops, or batteries are in capitals and are shown on the left. Companies, troops, batteries or platoons (not separate), and other elements of a unit which are designated by name instead of by letter (for example, "Antitank Company" or "Headquarters and Service Troop"), are designated by the use of the proper abbreviation on the left.

(4) Abbreviations for explanatory purposes are shown on the right (see sec. VI). Abbreviations are used instead of symbols to show information that cannot be indicated by a single symbol.

(5) Calibers are shown by numbers and unit of measure, as 37-mm, 155-mm, 12-in., .50-in. and are usually placed under the symbol. Often the unit of measure is omitted.

(6) In order to clarify the use of the various symbols and to insure uniformity, the following diagrams are inserted as a guide:
