Introduced in the early 2000s, the ACU (Army Combat Uniform) is current United States Army forces battle uniform, consisting of combat shirt and cargo trousers, and the successor to both the classic Battle Dress Uniform (BDU) and Desert Camouflage Uniform (DCU). Featuring several notable design changes, ACU shirts and combat trousers have all the features that distinguish Army Combat Uniform from its predecessors. The shirt goes with a mandarin collar and zippered front closure covered with a hook-and-loop flap, tilted chest and sleeve pockets, hook-and-loop adjustable cuffs, elbow pads pockets, a 3-slot pen pocket on the left arm and loop plates to attach name tapes, rank insignia, morale patches and tabs. ACU trousers come with two thigh pockets, tilted forward for easy access and with elastic drawstring and hook-and-loop closure for secure carry when on the move, two calf pockets (one on each leg) with a hook-and-loop closure, as well as hook-and-loop pouches designed for knee pad inserts. All those characteristics are present in MFH combat shirt and cargo trousers, now available at Military 1st online store. Moreover, innovative A-TACS LE camo works well in the urban environment, with changeable lighting and shading.
