The Army Combat Shirt, or ACS is a flame-resistant shirt developed for the United States Army as an addition to the Army Combat Uniform. The ACS is a stand-alone shirt designed specifically for use with Improved Outer Tactical Vest armor in warm and hot weather. It is intended to greatly increase user comfort through the use of lightweight, moisture-wicking, and breathable fabrics. The ACS was created in conjunction with the USMC’s Flame Resistant Organizational Gear (FROG). The ACS, in conjunction with the ACU trousers, provides head-to-toe protection against burns.
Design
The torso of the shirt is foliage green with the Army Strong logo centered on the chest (a feature deleted in the latest versions); the arms are in the Universal Camouflage Pattern similar to the Army Combat Uniform, with integrated anti-abrasion elbow pads. No-seam shoulders minimize rubbing or chafing against armor. Other features include a double pen pocket on the lower arm, zippered storage pockets on the upper arm, concealable infrared identification tabs, and a place to attach name, rank, and flag on the upper arm.
