Developed in the late 1980s and first issued in very limited quantity in 1990 as experimental test patterns, the DCU and its camouflage scheme, officially known as the Desert Camouflage Pattern, and also known colloquially as "coffee stain camouflage", was developed to replace the six-color desert camouflage "chocolate-chip camouflage" uniform, which was deemed unsuitable for most desert combat theaters. As opposed to the original six-color DBDU, which was meant for a rockier and elevated desert battlefield that was often not encountered, the DCU was created primarily for a lower, more open, and less rocky desert battlefield space which became a common sight throughout the Persian Gulf War. As a replacement pattern, this meant a new arid region had to be utilized to test the effectiveness of the DCU. Desert soil samples from parts of the Middle East, namely Saudi Arabia, and Kuwait, were used as testing locations to find the appropriate color palettes.
