If abbreviations are used, the word or words abbreviated are to be written in full on the first appearance, followed by the appropriate abbreviation in parentheses. Abbreviations standing for combinations of words are written in uppercase letters without spaces or punctuation (for example, Supreme Headquarters Allied Powers Europe (SHAPE)). Abbreviations of commonly used international metric terms may be used in Army written correspondence.
f. As governed by Quadripartite Standardization Agreement (QSTAG) 163, the following abbreviations may be used in military communications among United States, United Kingdom, Canadian, and Australian Armies —
(1) Those printed in chapter 2 .
(2) Those common to technical areas and used among similar offices.
g. The short form for abbreviating the grade of rank titles of colonel and below may be used when abbreviation is desired for official correspondence, literature, personal correspondence, automatic data processing (ADP) applications, and other areas where space is limited. The full grade of rank title will be used when corresponding with the general public and non-DOD agencies. The full general officer title will be used on official correspondence. The short form of abbreviating general officer grade of rank (GEN, LTG, MG, BG) may be used on informal correspondence and personal correspondence as desired. Short form abbreviations for military grade of rank are located at https://www2.arims.army.mil/abbreviation.
h. Abbreviations, brevity codes, and acronyms not contained in this regulation or the official RMDA database may be used within DA under the following conditions:
(1) When needed to meet electronic financial management requirements.
(2) In correspondence between offices and activities in the same scientific, technical field, or functional program where specialized abbreviations are developed.
(3) To process supply requisitions as prescribed in DA directives.
(4) When commonly used and listed in standard dictionaries and when they are not in conflict with this regulation.
To ensure uniform treatment in forming and using abbreviations, brevity codes, and acronyms, follow guidance below.
(1) Words or phrases containing less than seven letters should be avoided.
(2) The length of an abbreviation, brevity code, or acronym should be limited to avoid clumsiness and confusion.
(3) The term for which the ABCA has been developed must appear subsequently in the document (that is, if the term only appears once do not indicate a shortened form).
b. Existing words, abbreviations, and brevity codes.
(1) Brevity codes or acronyms that form existing words should be avoided.
(2) Brevity codes and acronyms identical with those authorized for other terms and phrases should be avoided. Identical terms/phrases will not be authorized unless the meanings are so different in context that there is no possibility of confusion.
c. Derivation. Nouns will be listed in the singular form and verbs in the present tense. Form plurals of brevity codes and acronyms by adding a lower case "s" (for example, major Army commands (MACOMs).
d. Combinations. Authorized abbreviations may be combined if —
(1) The resulting abbreviation or brevity code has not already been assigned a different meaning.
(2) The entire phrase or sentence has not been assigned a different abbreviation or brevity code (for example, AG is the authorized acronym for Adjutant General). (Abbreviations and brevity codes designated for groups of words must not be separated and used singularly. For example, the "A" in "AG" stands for "adjutant" in " Adjutant General," but if the word "adjutant" is abbreviated, "adj" must be used.)
e. Periods. A period will be used after an abbreviation, brevity code, or acronym only when it ends a sentence, or if the absence of a period would cause confusion, or when prescribed by the United States Government Printing Office Style Manual. For example, United States is abbreviated U.S. when part of a title that has other words spelled out, such as in U.S. Code or U.S. Army Reserve Center. When used as part of a brevity code such as USC ( United States Code ) or an acronym such as USARC (United States Army Reserve Center), the periods are omitted.
f. Capitalization. In general, abbreviated words should follow the capitalization of the word or words abbreviated; acronyms and brevity codes are normally in capital letters.
g. Scope. Abbreviations and brevity codes recommended for inclusion in this regulation will —
(1) Have Army-wide application.
(2) Not be unique to a single branch, department, or technical activity.
h. Abbreviations, brevity codes, and acronyms.
(1) Abbreviations normally will not be used in the text of written communications. They may be used in tables and figures and must be explained in a note or legend accompanying the table or figure. Abbreviated words should follow the capitalization of the word or words abbreviated, except when they are abbreviations for proper nouns that will begin with an upper case letter (for example, evac for evacuation; Eur for Europe).
(2) The meanings of brevity codes and acronyms used in Army written communications will be spelled out the first time that they appear, followed by the brevity code, or acronym in parentheses.
(3) Brevity codes will normally consist entirely of upper case letters (for example, TRADOC). Exceptions to this general rule may be made in the interest of clarity and conciseness. These exceptions will usually involve the use of the ampersand (&), numerals, or prepositions such as of, for, in, and at. Examples follow:
(a) Assistant Secretary of the Army, Financial Management and Comptroller — ASA (FM&C).
(b) Command, Control, Communications, Computers and Information Technology — C4/IT.
(c) Chief of Staff — CofS.
(4) Acronyms will consist entirely of upper case letters comprised of the first letters of a title, or a series of words. Acronyms may or may not include the first letter of prepositions and conjunctions in a series of words. An acronym should be pronounceable as a word (for example, RSOP — reconnaissance, selection, and occupation of position; ACTS-Army Criteria Tracking System).
(5) When spelled out in text or in glossaries, the meanings of abbreviations, brevity codes, and acronyms will follow generally accepted rules for capitalization. The practice of capitalizing all letters, or indiscriminately capitalizing the first letter of each word in a meaning, is not acceptable in Army publications, records, correspondence, messages, plans, orders, and reports. See table 1 for examples of acceptable and unacceptable capitalization of meanings.
Additions, deletions, and/or changes to the Army abbreviations,
brevity codes, and acronyms may be listed on a

An abbreviation is a shortened form of a word or phrase. For example, appt - appointment, assgd - assigned, or PA - Pennsylvania.
An acronym is a word formed from the initial letters of a name or parts of a series of words. For example, ACTS means Army Criteria Tracking System; ARIMS means Army Records Information Management System; and ASAP means as soon as possible.
A brevity code is the shortened form of a frequently used phrase, sentence, or group of sentences, normally consisting entirely of upper case letters; for example, COMSEC means communications security, REFRAD means release from active duty, and SIGINT means signals intelligence. When originating brevity codes: (1) Use letters that convey the meaning of the language they represent. (2) Do not represent the same word with more than one brevity code. (3) Make the first letter of the brevity code and the first letter of the phrase should be the same.
