in directives per this Manual and the U.S. Government Printing
Office Style Manual. JCS Pub 1, Department of Defense Dictionary
of Military and Associated Terms, should be consulted for usage
and definition of military terms.
2. Well-recognized abbreviations or acronyms which definitely
fall into one of the following categories may be used in the
preparation of correspondence, messages, and directives when they
will serve a useful purpose:
a. Abbreviations for points of the compass and map
coordinates.
b. Authorized model designations and symbols for common
types of aircraft, ships, or vehicles.
c. Abbreviations commonly used for geographical locations
and standard English dictionary abbreviations.
d. Other technical abbreviations or acronyms customarily
used by the specialists and technicians when communicating with
activities or persons in the same field as that of the
originator, and to no others.
3. Abbreviations and acronyms other than those outlined in
paragraph 6002 may be used in the text of correspondence,
messages, and directives, after they have been initially spelled
out and identified in each item of correspondence, message, and
directive. For example, ICAO could be used in a letter, but only
if that letter's first reference to the organization read:
International/Civil Aviation Organization (ICAO).
4. In naval correspondence and directives, use a period after
abbreviations that are complete words in themselves; e.g.,
amend., art., par., fig., etc. Do not use punctuation after an
abbreviation when preparing naval messages and AA Forms.
5. Abbreviations, acronyms and short titles which have, through
years of joint usage, become self-evident, unequivocal, and
universally known, are acceptable for joint use within and among
the services. Do not use an abbreviation or acronym if there is
any doubt that it will be easily and readily understood. Such
abbreviations or acronyms peculiar to the U.S. Navy and U.S.
Marine Corps may be used under the same conditions, but only
within the Department of the Navy.
