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^[1]

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.
