US M2/M2A1 Flamethrower
The US M2/M2A1 flamethrower, a significant WWII weapon, evolved rapidly from the unreliable M1. It utilized gelled fuel (napalm) for extended range and featured a reliable pyrotechnic ignition system. Safety improvements were made from the M2 to the M2A1, including a vent cap replacing the rupture disc.
