ACU camouflage is a type of camouflage pattern used by the U.S. Army. The pattern was first issued in the early 2000s and is used for both Army Combat Uniforms (ACUs) and Army Combat Helmets (ACHs). ACU camouflage is designed to reduce the visual and near-infrared signature of a person wearing it in many different environments. It uses a blend of greens, tans, grays and black to create a unique three-color digital pattern. The pattern also consists of smaller black and gray pixels within a larger pixel pattern. The material used for ACU camouflage is lightweight, breathable and durable, making it ideal for use in hot and humid climates. Additionally, ACU camouflage is treated with a waterproofing agent to help keep soldiers dry and comfortable in wet weather. ACU camouflage is an important tool for U.S. soldiers in helping them remain undetected while on combat missions. By providing them with this type of camouflage, the U.S. Army can ensure its troops are well-equipped to face any challenge they may encounter.
