The Airman Battle Uniform (ABU) is a U.S. camouflage combat uniform worn by members of the Civil Air Patrol. The uniform was worn by United States Air Force Airmen, United States Space Force Guardians, and some civilian employees of the U.S. Department of Defense (DoD) until April 2021. It replaced the Battle Dress Uniform and Desert Camouflage Uniform on 1 November 2011 after a four-year phase-in period. On 14 May 2018, The U.S. Air Force announced that all airmen will transition from the Airman Battle Uniform to the OCP Uniform. All airmen have been permitted to wear the OCP Uniform since 1 October 2018, and the wear out date for the ABU was 1 April 2021.
