A combat uniform, field uniform, or battle dress, is a type of uniform used in combat, as opposed to dress uniforms worn in functions and parades.

The combat uniform is generally camouflaged, either in monochrome such as a shade of green or brown to approximate the background, or in a disruptive pattern.

Contrary to dress uniforms, the combat uniform is usually made from cotton (or in modern times a cotton blend), and to a looser and more comfortable cut.
