Operational Camouflage Pattern (OCP), originally codenamed Scorpion W2, is a military camouflage pattern adopted in 2015 by the United States Army for use as the U.S. Army’s main camouflage pattern on the Army Combat Uniform (ACU). This pattern officially replaced the U.S. Army’s previous Universal Camouflage Pattern (UCP) as the official combat uniform pattern for most U.S. soldiers at the end of September 2019.

The pattern also superseded the closely related MultiCam, a pattern previously used for troops deploying to Afghanistan. The United States Air Force is also replacing their Airman Battle Uniform with the ACU in OCP after positive feedback from airmen who wore the uniform while being deployed to Afghanistan with Army soldiers.

The original “Scorpion” pattern was developed by a joint venture of the Army’s Natick Labs and Crye Precision as part of the Objective Force Warrior (OFW) program more than a decade prior. Crye then modified it to create MultiCam for commercial sales. In July 2014, the Army announced that OCP could be used in the field by the summer of 2015.

In early April 2015, Army Chief of Staff Ray Odierno revealed that OCP uniforms were beginning to be issued to deployed soldiers going to Afghanistan, Iraq, Europe, and the Horn of Africa.[1] The OCP ACU became available for soldiers to purchase starting 1 July 2015.[2]
