An improved version of the earlier M1 and M1A1 man-portable flame thrower units developed by the U.S. in the early 1940s, the M2 became the standard flamethrower used by U.S. forces through the latter half of World War II, and saw continued use through the Korean and Vietnam Wars until it was phased out for the lighter M9. Unlike the electric ignition of the earlier M1 series, the M2 series utilized a spring loaded, match lit, five cell ignition cylinder installed within the ignition head of the "-2" designated wand (or gun group). In U.S. service, the flame thrower was used against dug in fortifications and tunnels, utilizing not only the heat generated by its projection but also the suffocating effects of the flames within confined spaces to incapacitate enemy combatants. This example is a Korean War era M2A1, which is largely similar to the World War II era M2 other than a simplified pack frame and improved gas tank valves. Features a rectangular tube steel pack frame with OD green web backing and quick detach shoulder straps, brass Chemical Warfare Service U.S.A. placard on the back of the frame marked "MONROE", "SERIAL 5460", and "LOT NY-1979-55", two fuel tanks with World War II era M2 pattern brass fuel cap and deflector tube fitted, central pressure tank, replacement hose coupler, cast aluminum "R.F.S. INC." marked "-2" wand, and fuel hose. Includes two Korean War era improves fuel tank valves, a non-functioning fuel tank pressure gauge, brass hose connection plug, two spare safety valves, spare regulator assembly, spare rubber washers, two BernzOmatic hand-held propane torch igniters (one fitted with a coupler for the front grip of the wand), a spare ignition shield cut for a torch muzzle, operator training instruction booklet, and ignition torch mounting instruction booklet.

Fine as professionally restored, with 70% plus of re-applied OD green paint remaining along with light spotting, minor pitting on the frame, minor fraying on the web straps, and scattered light handling marks. Wand is fine with 80% re-applied OD green paint with light flaking, grey patina on the aluminum components. The wand's grip safety, valve lever, and trigger rod appear mechanically sound. A seldom seen piece that would draw attention in any U.S. military collection!
