The ‘Night-Time Desert Grid’ pattern was introduced in the early 1980s on a two-piece trouser-and-parka uniform to be worn at night over the ‘six-color desert’ uniform. The design consisted of a base color over-dyed with two screens, forming a grid pattern with irregular blobs. The camouflage was designed specifically to help troops evade detection in the dark by night observation devices (NODs) but was discontinued in 1991, after the Gulf War.
