Definition of Aafes

The Army and Air Force Exchange Service (or AAFES) is an agency of the United States Department of Defense. Its mission is to provide quality merchandise and services of necessity and convenience to authorized customers at uniformly low prices, and to generate reasonable earnings to supplement appropriated funds for the support of United States Army and Air Force Morale, Welfare and Recreation (MWR) programs. These contributions to the Soldier and Airman and their families make AAFES a major non-pay benefit to customers. AAFES is headquartered in Dallas, Texas and is commanded by a Major General. The position of AAFES commander rotates between the Army and Air Force. The Navy operates the equivalent Navy Exchange (NEX), while the Marine Corps operates the Marine Corps Exchange (MCX).
