List of U.S. Department of Defense 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:
 * Nicknames - a combination of two separate unassociated and unclassified words (e.g. Polo and Step) assgned to represent a specific programme, special access programme, exercise, or activity.
 * Code words - a single classified word (e.g. BYEMAN) which identifies a specific special access programme 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 organisation 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.
