Army Combat Uniform
The Army Combat Uniform (ACU) and its flame-retardant variant, the Flame-Resistant Army Combat Uniform (FRACU), are the current battle uniforms worn by the United States Army. 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 the early 2000s, respectively. It features a number of design changes, as well as a different camouflage pattern from its predecessor. The ACU and its component materials are manufactured by the existing industrial infrastructure which produced the now-obsolete BDU. Official military-grade ACUs are made of 50% nylon and 50% cotton. All other blends are not official issue.
