US Army, M1941 Coleman Stove

During World War II, the U.S. government tasked Coleman to develop a compact stove for military use. The stove had to be lightweight, no larger than a quart-sized thermos bottle, burn any kind of fuel, and operate in weather from −60 to +125 °Fahrenheit. Within 60 days, Coleman came up with what became the G.I. Pocket Stove. Designated their Model 520 Coleman Military Burner, and referred to by the Army Quartermaster Corps as the M1941 Stove, the stove first saw service in November 1942 when 5,000 of the stoves accompanied U.S. forces during the invasion of North Africa. Over 1 million of the stoves wered produced for war use
