(abbreviated DBDU, often called Chocolate-Chip Camouflage, Cookie Dough Camouflage, or the Six-Color Desert Pattern) was the camouflage used by the United States military forces during the Gulf War era in the early 1990s. The camouflage received its nickname because it resembles chocolate-chip cookie dough. It is made up of a base pattern of light tan overlaid with broad swathes of pale olive green and wide two-tone bands of brown. Clusters of black-on-white spots are scattered over it.
The six-color desert pattern entered service in 1981 at the same time as the woodland BDUs and would be worn in limited numbers by U.S. troops taking part in the biennial Bright Star exercises in Egypt during the 1980s, and by FORSCOM peacekeepers in the Egyptian Sinai Desert, but issued in large numbers prior to the Gulf War.
Feedback from these users indicated that the design contrasted too much with the terrain, preventing the camouflage from blending in effectively. Anecdotal evidence suggested that the dark areas of the pattern warmed up more than the paler parts under desert sunlight, and retained the heat longer. The six colours were also more expensive to manufacture than three or four colors, and the need for a camouflage that would be suitable for use in any desert resulted in a requirement for a new desert camouflage uniform. The U.S. Army Natick Soldier Center began the search for a substitute. Samples of sand and earth from the Middle East were measured for optical and infrared reflectance, and seven trial patterns were created using these statistics. The patterns were evaluated in fourteen different desert locations and narrowed down to one favourite. The resulting "Desert Camouflage Pattern: Combat" was standardized in 1990, but was not ready before troops deployed to Saudi Arabia during the Gulf War of 1990-1991. Consequently U.S. forces wore the six colour BDUs during the campaign. During that war, after initiatives by General Norman Schwarzkopf, the six-color Desert BDU was produced in 100% cotton poplin without reinforcement panels in order to improve comfort in hot desert conditions. A total of 500,000 improved cotton BDUs were ordered. However, cost concerns caused the cotton six-color Desert BDU to be discontinued shortly after the Gulf war.
Both patterns were briefly used together during the transition period, most notably during Operation Restore Hope and Operation Gothic Serpent (some US Army Rangers during the latter occasionally wore the newer 3-color DCU's along with kevlar helmet covers retaining the old 6-color pattern). In the 2003 invasion of Iraq, the US Military used both the tri-color DCU and MARPAT camouflage patterns.
