Appendix:Glossary of military slang

Military slang is a set of colloquial terms which are unique to or which originated with military personnel. They are often abbreviations or derivatives of the NATO Phonetic Alphabet, or otherwise incorporating aspects of formal military concepts and terms. Military slang is also used to reinforce the (usually friendly) interservice rivalries. Some of these terms have been considered gregarious to varying degrees and attempts have been made to eliminate them.

For the purposes of this article, "military slang" includes slang used by any English-speaking armed forces (armies, navies, air forces).
