Battle Dress Uniform
The U.S. military has run trials of many camouflage patterns (some being used by foreign militaries), and issued environment-specific uniforms, notably the six-color Desert Battle Dress Uniform (DBDU), nicknamed the "chocolate chip camouflage", designed in 1962, and the "nighttime desert grid" (NCDBDU). Both uniforms were used in 1991, during the Persian Gulf War. These Desert BDUs were discontinued after the war.
