From the Call of Duty Wiki
In real life, Desert Camouflage is a pattern of camouflage used by the military for use in desert and urban desert environments. It uses similar shades as those seen in a natural desert environment in order to allow the camouflaged person or item to blend in with its surroundings. The in-game camo is NOT the US Army tri-color Desert Combat Uniform (DCU) camo (it features two shades of brown and lacks the light green color).
[edit] In Game
In Call of Duty 4: Modern Warfare, desert camouflage is available on any weapon as a default. It can only be used in online multiplayer.
This variety of camouflage is not commonly used by experienced players, who are more likely to use patterns obtained through awards. Camouflage is used more as a sign of rank than as an actual tactic, and, therefore, desert camouflage is quickly discarded once higher camouflage patterns are attained. Another reason why desert camouflage is infrequently used may be that players regard it as aesthetically inferior to the other, unlockable, camouflages.
