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

    This is an incomplete list, which may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries. Please observe the definition of the list when adding or editing entries.
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:
* Nicknames – a combination of two separate unassociated and unclassified words (e.g. Polo and Step) assigned to represent a specific program, special access program, exercise, or activity.
* Code words – a single classified word (e.g. BYEMAN) which identifies a specific special access program or portion. A list of several such code words can be seen at Byeman Control System.
* Exercise terms – a combination of two words, normally unclassified, used exclusively to designate an exercise or test
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.
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.
