A great video of the US Military M3 84mm Recoilless Rifle. The Carl Gustaf (Swedish pronunciation: [ˈkʰɑːɭ ˈɡɵ̞stɑːv]; also known as, Gustaf Bazooka and M2CG) is an 84 mm man-portable reusable anti-tank recoilless rifle produced by Saab Bofors Dynamics (formerly Bofors Anti-Armour AB) in Sweden. Although most rounds fired by the Carl Gustaf work on the classic recoilless principle, modern rounds sometimes add a post-firing booster that technically make it a rocket launcher.
The first prototype of the Carl Gustaf was produced in 1946 as a lightweight anti-armor weapon, one of many similar designs of that era. While similar weapons have generally disappeared from service, the Carl Gustaf remains in widespread use today. A combination of light weight, low cost and widely varied ammunition types, makes the Carl Gustaf extremely flexible and able to be used in a wide variety of roles where single-purpose weapons like the M72 LAW passed out of service as newer tank designs rendered them ineffective.
In its country of origin, it is officially named Grg m/48 (Granatgevär – "grenade rifle", model 1948). British troops refer to it as the "Charlie G", while Canadian troops often refer to it as "Carl G". In U.S. military service, it is known as the "M3 Multi-Role Anti-Armor Anti-Personnel Weapon System" (MAAWS) or "Ranger Anti-tank Weapons System" (RAWS), but is often called the Gustaf or "the Goose" or simply the "Carl Johnson" by American servicemembers. In Australia, it is irreverently known as "Charlie Gutsache" (guts ache, slang for stomach pain).
In May 2009, U.S. Army Special Forces soldiers train with the Carl Gustaf recoilless rifle in Basra, Iraq, during the Iraq War. Note the firing position and recoilless backblast.
The basic weapon consists of the main tube with the breech-mounted Venturi recoil damper, with two grips near the front and a shoulder mount. The weapon is fitted with iron sights, but is normally aimed with the attached 3× optical sight with a 17 degree (300 mrad) field of view. The most modern variants fielded by Swedish rifle companies have been fitted with the Swedish Aimpoint sighting system. Luminous front and rear sight inserts are available for the iron sights when aiming at night, and an image intensification system may also be used.
The Carl Gustaf can be fired from the standing, kneeling, sitting or prone positions, and a bipod may be attached in front of the shoulder piece. An operating handle called the "Venturi lock" is used to move the hinged breech to one side for reloading. The weapon is normally operated by a two-man crew, one carrying and firing the weapon, the other carrying ammunition and reloading.
