The B-300 is a reusable man-portable anti-tank weapon system developed by Israel Military Industries in the late 1970s for use by the Israel Defense Forces. The B-300 can be carried and operated by a single operator and is effective to approximately 400 meters (1,312 ft).[2] Pre-packaged munitions and simple operating mechanisms make the weapon quite versatile, permitting use by airborne, motorized, and ground troops alike. When defence publications first heard reports of the B-300 in the early 1980s, various reports stated in error that it was an Israeli improved and manufactured version of the Russian RPG-7.[3]
