M2 flamethrower

The M2 flamethrower was an American-made portable flamethrower that was used during World War II. It was the successor to the M1 and M1A1 flamethrowers. Although it could only shoot fire for around 7 seconds and the flame was only effective out to around 20–40 meters. However, with the arrival of flamethrower tanks, the need for flamethrower-carrying infantrymen to expose themselves to enemy fire was greatly reduced.
Though some M2s were sold off, the majority were scrapped (thrown away) when they were declared obsolete (uneeded).

In these models the igniter controls are on the front handgrip, arranged in the same way as the rear handgrip controls. The M2 was replaced by the M9A1-7 flamethrower which was used in Vietnam. The M9A1-7 was replaced by the M202A1 FLASH.
