The M3 Carl Gustav is a Multi-role Anti-armor Anti-personnel Weapon System (MAAWS), which was specially designed for the infantry to attack bunkers, armored vehicles, pillboxes, and machine gun nests. Developed from the M2, it is manufactured by the Swedish firm Saab Bofors Dynamics since 1991. It is in service with the armed forces of Sweden, Germany, Austria, Australia, and the USA. It has successfully been used in combat missions by the US Special Forces and the 75th Ranger Regiment in Afghanistan against the Taliban guerrillas. Technically and basically, the M3 is a recoilless rifle that fires 84mm-caliber ammunition, which is loaded in a breech at the back of the tube. The system allows some of the ignition propellant gases to escape through the rear, neutralizing most of the recoil. The weapon uses a rifled tube, which imparts a rotatory movement to stabilize the projectile as it travels through the air at 800 feet per second (250 m/s). The rifling spare the need of fins on the projectile. Thus, this Swedish infantry weapon can knock out a steel main battle tank at 700 m away, with extreme accuracy as it is fitted with laser rangefinder, image intensification system, and optical 3x sights.
