Frequently employed in WWII flamethrowers were first deployed by the German Imperial army in the Great War as part of the solution to reachdecisive breakthroughs. Their fire was feared with good reason:The 4th and 5th Marine Divisions emphasized the greater effectiveness of the main armament type as opposed to the auxiliary flame thrower, of which the 4th Division had twenty-four. These divisions recommended more large capacity flame throwers and their incorporation as organic equipment in all tank battalions.78 Although the 3d Marine Division entered the Iwo Jima operation without main armament flame throwers, it was later on able to borrow some from the other divisions. In its opinion this type was better against enemy defenses than the auxiliary bow gun flame throwers with their shorter range and limited traverse.79
After-action reports for the Iwo Jima operation attested to the value of the flame weapons. Of the two types, the mechanized flame thrower seemed to have come out on top. One battalion commander called it the "best single weapon of the operation."80 The V Amphibious Corps report referred to the mechanized weapon as the "only effective means"
On 15 December troops of the 126th Infantry, 3 2d Division, were halted in the Ormoc corridor by strong resistance from a pillbox and riflemen situated about twenty yards below the crest of a hill. After one attempt to overcome these defenses had failed, the regiment formed an assault party of fifteen riflemen, a bazooka team, and two flame thrower operators. The party crept around the enemy and opened fire simultaneously with grenades, bazookas, and flame throwers. One flame thrower operator directed his fire on the pillbox, while the other sprayed the rifle positions. The attacking riflemen found that the badly burned and demoralized Japanese offered little resistance.43

The original pioneers incorporated the portable version (an not only) also in WWII into their tactical doctrine, visible in this training video:

No Western army has a "classic" flamethrower in it's inventary but the question remains: Is it still a viable weapon system?
