The AMMO, commonly known as the Munitions Squadron or "Ammo Troop," is a vital unit within the United States Air Force responsible for the assembly, inspection, storage, and delivery of munitions. Established in the mid-20th century, AMMO units have played a crucial role in every major conflict involving U.S. airpower, from the Vietnam War to present-day operations. These units ensure that all types of ordnance—from small arms ammunition to precision-guided bombs—are safely prepared and ready for use by combat aircraft. The AMMO motto, “IYAAYAS” (If You Ain’t Ammo, You Ain’t Shit), reflects the pride and esprit de corps of these highly trained specialists who keep the Air Force armed and ready.
