Army Air Defense Artillery pretty much abandoned guns in the Fifties in favor of missiles like the Nike and the Hawk. But both the M42 Duster and the M45 Quad Fifty proved themselves useful in Viet Nam. Despite the popular notion that it was the Huey that hauled everything, the truth is an awful lot of the "beans and bullets" traveled in the lowly deuce and a half. Trucks travel by road and roads are where the ambush will be. No airplanes to shoot at, but the truck carrying a Quad Fifty found a new role.
