Military organizations, like nearly all large exclusive organizations, develop slang as means of self-identification.

Military slang is also used to reinforce the (usually friendly) interservice rivalries. Some of these terms have been considered derogatory to varying degrees and attempts were made to eliminate them. Those attempts have failed because many service members take a certain perverse pleasure in the sense of shared hardship which the nickname implies.

Military slang has often been incorporated into wider usage. See also: List of U.S. Army acronyms and expressions , American English, British English. For British Army slang see the Forces Dictionary on http://www.biscuitsbrown.com. For Covey Crump see the Navy Slang sub-section under the Naval Life section on the Royal Navy website http://www.royal-navy.mod.uk.
