The Desert Camouflage Uniform (DCU) is a variant of the standard Battle Dress Uniform designed for use in desert environments. It is often employed by SG teams.
History
DCUs have been employed on many occasions by Stargate Command, as arid planets are common destinations in the Milky Way's Stargate network.
A large supply of desert uniforms were part of the Destiny expedition supplies. They are often used by the civilian personnel when travelling offworld, regardless of the conditions.
