What are army fatigue cargo pants?

Army fatigue cargo pants are pants for men or women traditionally made from fabric with shades of green, brown, tan and black that have cargo pockets on the exterior thigh. The pants are made from a nylon-cotton blend.

The green, brown, tan and black nylon-cotton fabric is known as woodland pattern camouflage, and officially became part of the Army's Battle Dress Uniform trousers in 1981. At the same time, a fabric with only tan, brown and black shades known as the Desert Camouflage Uniform was introduced. In 2004, the Army introduced the Army Combat Uniform cargo pants which had a gray, tan and green digital pattern.
