ACU

The Universal Camouflage Pattern (UCP) is a digital military camouflage pattern formerly used by the United States Army in their Army Combat Uniform.

The pattern was chosen after laboratory and field tests from 2003 to 2004 showed it to provide the best concealment in many different operational environments. It beat ten other patterns (though UCP may still have been adopted without field testing against other patterns because senior military leaders liked it).

Its pixelated pattern is similar to the MARPAT and CADPAT camouflage patterns used by the United States Marine Corps and the Canadian Armed Forces, respectively.
