M1 flamethrower

The M1 and its improved successor the M1A1 were portable flamethrowers developed by the United States during World War II. Development began in July 1940 under the designation E1, and the M1 was formally adopted in August 1941, weighing 72 pounds, carrying five gallons of fuel and reaching a range of 15 meters. The lighter M1A1, adopted in 1943 at 65 pounds, extended the range to 45 meters and fired thickened fuel, or napalm; both weapons saw limited use in Europe but were used extensively against Japanese pillboxes and fortifications in the Pacific theater before the M2 flamethrower replaced them later in the war.
