m202 flash
The M202 FLASH (FLame Assault Shoulder Weapon) is an American four-barrelled rocket launcher designed to fire incendiary projectiles. It can fire its rockets either individually or simultaneously and was reloaded from the rear using a clip of four rockets.
The weapon is recognizable by its boxy shape with a pistol grip, squared-off front profile, down-folding lids on both rear and front, as well as its depiction in films like Commando.
