History of the M2-2 Flamethrower

“The M2 flamethrower was an American man-portable backpack flamethrower that was used in World War II. It was the successor to the M1 and M1A1 flamethrowers. The Flamethrower M2 was developed in 1944 to replace the M1 that was plagued with problems and it was in direct response to those problems that the M2 was made extremely reliable. The M2 became the standard flamethrower of WWII and continued in use until completely replaced by the M9-7 in the beginning of the Vietnam War.” –Military Factory

History of Flamethrowers

It goes without saying that fire had always maintained a prominent place on the battlefield even dating as far back to ancient times. It was readily available and the only issue revolved around its adequate delivery onto the heads of enemy formations. “Liquid fire” was nothing new by the time of World War 1 and the Germans used such a flame-spewing weapons to good effect in the trenches against their French enemies. While these systems were large and cumbersome components, they instilled much fear against their intended targets in the fire zone and served as a tremendous psychological presence nonetheless – fire, it seemed, had a way of motivating any living thing to move from its held ground. –Military Factory
