Frog Skin, also known as Duck Hunter, is a battledress camouflage pattern^[2] with mottle and disruptive coloration to blend into the environment similar to a frog's crypsis skin.^[3]

The M1942 Frog Skin pattern was the United States military's first attempt at disruptive coloration camouflage.^[2]

The US Army began experiments with camouflage in 1940–1941.^[4]

In 1942, the Marine Raiders were the first issued the Frog Skin uniform, which was reversible with a five-color jungle pattern on a green background on one side and a three-color beach pattern with a tan background on the other side.^[5][2][6] The pattern was made for the M1942 Reversible Spot Pattern and P42 Camo utility uniform based on the herringbone twill (HBT) cotton fabric.^[1]

The Paramarines had their own pattern uniform in the same camouflage pattern in the Bougainville campaign.^{[citation needed]}

The uniform was worn by the Marines in other campaigns, notably the Battle of Tarawa. In the ETO certain US Infantry divisions wore the uniform in France, but the uniform was withdrawn for resembling German camouflaged uniforms.^[7]

By January 1944, production of the pattern was stopped with the uniforms being sold as surplus.^[8] It found its way to civilians, including duck hunters.^[8] This led to the adoption of the name Duck Hunter camo.^[9]

The United States used the pattern in limited use in the Korean War for Marines for helmets as helmet covers.^[1][10]

The Frog Skin pattern traveled to France who issued it to their 1st Foreign Parachute Regiment and 2nd Foreign Parachute Regiment during the First Indochina War.^[11]

In 1961, the Cuban exiles Brigade 2506 were issued the Frog Skin pattern by the Central Intelligence Agency (CIA) for the Bay of Pigs Invasion.^[11]

During the Vietnam War, the United States Special Forces issued Frog Skin to the Montagnard for their guerrilla warfare activities.^[11] Navy SEALs and Rangers resorted to using the camo due to a lack of a standard camouflage.^[8] Army Special Forces advisers, sailors and Marines attached to the Military Assistance Command Vietnam — Naval Advisory Group and the CIDG also used it before Tigerstripe uniforms were issued.^[1]

The design was done by Norvell Gillespie, a civilian horticulturist and the gardening editor for Better Homes & Gardens magazine, at the request of the US military.^[1] 150,000 uniforms in the pattern were ordered.^[1] Feedback from American soldiers who used it said that the lighter color base stood out when moving in the dark jungle.^[8]

The German created Flecktarn is a multi-colored mottled pattern, which creates a dithering effect by eliminating hard color boundaries and has been adopted by many countries. The Australian Defence Force Disruptive Pattern Camouflage Uniform is a five-color mottle pattern, which utilizes disruptive coloration to break up a soldiers outline with a strongly contrasting design.

The duck hunter camouflage pattern was first seen with some American units fighting in Vietnam, based on the frog skin pattern.^[1]
