United States Army- ACU- Full Combat Uniform

The Army Combat Uniform (ACU), also known as the Airman Combat Uniform (ACU) in the Air Force, and its flame-retardant variant, the Flame-Resistant Army Combat Uniform (FRACU), are the current combat uniforms worn by the United States Army and U.S. Air Force.

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.

Soldiers of the U.S. Army will no longer wear the Universal Camouflage Pattern, otherwise known as the Army Combat Uniform (ACU) pattern or Digital Camouflage as of October 1, 2019.

Officials have been phasing out the pattern since 2014, replacing it with the “Scorpion” pattern, otherwise known as the Operational Camouflage Pattern (OCP). The OCP has been generally regarded as a major improvement over the ACU, according to Soldiers.
