In 1942, the Marine Raiders were the first to be issued the WWII camo pattern known as “Frogskin”. Designed by Norvell Gillespie, a civilian horticulturist at the request of the US Military. The Frogskin pattern was the United States military's first attempt at disruptive coloration camouflage, the Frogskin name was given to the pattern due to the similarity it has to a frog’s skin and the ability to blend into and hide in its environment.

Primarily associated with WWII US Marine Corps troops in the Pacific and the US Army’s 2nd Armored Division as well as the 41st Infantry Regiment in the Normandy Campaign, this pattern did not have a long run with the US Military. In 1944 production of the pattern was stopped and the uniforms began to be sold as surplus and issued to allied countries where the pattern would make short appearances throughout history. Through the surplus world this pattern would make its may to civilian hands and became popular among duck hunters and led to the adoption of the name Duck Hunter camo.
