A U.S. Marine flamethrower, one of the many who had the weapon proven to be quite effective in winning the month long Battle of Iwo Jima, 1945

Here is my colorized take on a photo showing a typical U.S. Marine flamethrower. The M2 flamethrower served as the single most effective weapon in major Iwo Jima engagements against Japanese troops who hid in pillboxes, caves, buildings, and bunkers that have proven to be invulnerable to earlier bombing runs, artillery and naval bombardment.
