The Army Combat Uniform (ACU) is the current combat uniform worn by the United States Army, U.S. Air Force, U.S. Space Force and some elements of the U.S. Coast Guard. Within the Air Force and Space Force, it is referred to as the OCP (Operational Camouflage Pattern) Uniform, rather than the Army Combat Uniform.

First unveiled in June 2004, it is the successor to the Battle Dress Uniform (BDU) and Desert Camouflage Uniform (DCU) worn from the 1980s and 1990s through to the mid-2000s, respectively. It is also the successor to the Airman Battle Uniform for the U.S. Air Force. Initially, it was made with the Universal Camouflage Pattern (UCP), but due to its ineffectiveness it was replaced by the Operational Camouflage Pattern (OCP).
