List of U.S. Department of Defense and partner code names

This is an incomplete list of U.S. Department of Defense code names primarily the two-word series variety.

Officially, Arkin (2005) says that there are three types of code name: In 1975, the Joint Chiefs of Staff introduced the Code Word, Nickname, and Exercise Term System (NICKA) which automated the assignment of names.

NICKA gives each DOD organization a series of two-letter alphabetic sequences, requiring each 'first word' or a nickname to begin with a letter pair.

For example, AG through AL was assigned to United States Joint Forces Command.

[1] The general system described above is now in use by NATO, the United Kingdom, Canada (Atlantic Guard, Atlantic Spear, Atlantic Shield) Australia and New Zealand, and allies/partners including countries like Sweden.
