The Carl Gustaf 8.4 cm recoilless rifle is a Swedish-developed 84 mm caliber shoulder-fired recoilless rifle, initially developed by the Royal Swedish Army Materiel Administration during the second half of the 1940s as a crew-served man-portable infantry support gun for close-range multi-role anti-armour, anti-personnel, battlefield illumination, smoke screening and marking fire, which has seen great export success around the globe and continues to be a popular multi-purpose support weapon in use by many nations.
