Our American woodland camouflage pattern is inspired by the U.S. Woodland camouflage pattern that was used as the default camouflage pattern issued to the United States Armed Forces from 1981, with the issue of the Battle Dress Uniform, until its replacement in the mid to late 2000s. It is a four color, high contrast disruptive pattern with irregular markings in green, brown, sand and black. It is also known unofficially by its colloquial moniker of "M81", though this term was not officially used by the U.S. military. Although completely phased out of frontline use in the U.S. Armed Forces, U.S. Woodland is still used on some limited level by some branches such as MOPP suits, equipment and vests left over while some modernized uniforms (either BDU or commercial) were worn specifically by special forces such as USMC Forces Special Operations Command and United States Navy Seabees.
