The ACU originally used the Universal Camouflage Pattern (UCP), which used a pixelated pattern of tan, gray and green (Desert Sand 500, Urban Gray 501 and Foliage Green 502) and was intended to work in desert, woodland, and urban environments.
For uniforms, the pattern was fully phased out and replaced by the Operational Camouflage Pattern on 30 September 2019, though UCP remains in service in limited capacities such as on some cold weather overgear and older body armor.
