Several camouflage designs were tested by the US Army during the Second World War (circa 1942), none of which were ever adopted. The only pattern that we have a name for has been called the MacLaren pattern (presumably named after its developer). The design featured olive green spots printed over reddish-brown blotches with undefined edges, on a khaki or pale green background. Although full uniforms were produced, very few have survived into the present era.
