The M72 LAW (Light Anti-Tank Weapon, also referred to as the Light Anti-Armor Weapon or LAW) is a portable one-shot 66 mm unguided anti-tank weapon, designed in the United States by Frank Spinale et al while with the Hesse-Eastern Division of Norris Thermadore, produced by Nammo Raufoss AS in Norway.
The LAW replaced the bazooka as the United States Army's primary anti-tank weapon after the Korean War. It was intended that it would be replaced in service by the FGR-17 Viper (which would also replace the FGM-77 Dragon), but this program was cancelled and the M136 AT4 was introduced in its place. It can be compared with the better-known Soviet RPG-7 rocket propelled grenade, which uses a booster charge in addition to a rocket.
