Although the flamethrower atttacks force horror, but teammate of easy also in real action accidentally injure even accidentally injure launchs him hand, because launch a hand to was equivalent to carrying a gasoline tank that explodes possibly at any time on the shoulder, and its ejective blaze is to be aimed at roughly, unlike bullet shoots specific target euqally. In Pacific Ocean war, flamethrower of beautiful for military use makes do hide in cave the Japanese army of medium, close Lin Zhong, often be being burned is a brood, yield Japanese army become terror-stricken at the news. But the U.S. Army is in actual combat more and more discover flamethrower is put in insecure element, so after the Second World War, american spent many time and energy to undertake transforming to the flamethrower, make edge tool of this fighting at close quarters more safe, also raise range at the same time. 20 centuries 60 time later period, the U.S. Army developed M-202 shoulder to shoot model blaze is atttacked implement. Of tradition of unlike of this light-duty portable flamethrower so cumbersome. On the other hand, traditional flamethrower can be only inside very short range successive eject 9 seconds, and this ejector gush is gotten longer, still can gush has mephitis system. After 10 years, the U.S. Army applied M-202 flamethrower Vietnam battlefield, exhibit invincible might greatly in Vietnam bushfighting. To develop a flamethrower further fight advantage, the U.S. Army was made to ejector again improve further, make an emitter of relatively simple 4 canals rocket, with the incendiary that will launch 66 millimeter line of action. Differ with groovy flamethrower, more practical canal uses new-style M-202. The U.S. Army is in the forest with dense Vietnam, antitank like use M-72 incendiary blasts off like the rocket, this kind of incendiary uses TPA compound and not be tall explosion medicine and caky benzine. 3 second include in mixture base aluminous, this is one kind is different from caky petrolic compound, expose meet in air severe inflammation.

After Vietnam checks a success, the U.S. Army installed emitter of this kind of rocket in other department alignment again. The final version after improving, the name is M-202A1 FLASH. Besides can launch incendiary, this emitter still can lade emissive lachrymator is played. But the incendiary that blasts off as a result of this kind of emitter is too cruel, the Pentagon by force of pressure, begin disuse from 1987. Although see the U.S. Army uses a flamethrower on battlefield very hard nowadays, but M-202 is in the film and game however distinguish oneself, apply Waxinge to be in among them " assault team member " useful M-202 and adversary desperately setting, make a lot of people impressive.
