Military terms and symbols that are used by the U.S. Army have been compiled in an updated reference manual, along with acronyms and abbreviations. See ADRP 1-02, Terms and Military Symbols, December 2015.
Intended to foster a common vocabulary, the manual can also help outsiders to interpret distinctive Army expressions and patterns of speech.
The manual devotes several chapters to “military symbology.”
“A military symbol is a graphic representation of a unit, equipment, installation, activity, control measure, or tactical task relevant to military operations that is used for planning or to represent the common operational picture on a map, display, or overlay.”
“The symbology chapters (chapters 3 through 10) provide detailed requirements for composing and constructing symbols. The rules for building a set of military symbols allow enough flexibility for users to create any symbol to meet their operational needs,” the manual said.
