The M1942 Reversible Spot Pattern was the standard camouflage pattern of the United States Marine Corps during World War II. Notably, the M1942 Reversible Spot Pattern was widely used initially with the M1942 One-Piece Camouflage Suit as well as the M1942 M1 Helmet Cover, common with marines in the Pacific. The pattern consisted of a tan base with brown shapes on one side of whatever cloth it was printed on with a light brown base on the other with dark brown, light green, and dark green shapes. This allowed marines to wear the tan colored pattern during lands and in sandy environments while switching to the green and brown pattern for inland jungle areas.
