The M72 LAW (light anti-tank weapon, also referred to as the light anti-armor weapon or LAW as well as LAWS: light anti-armor weapons system) is a portable one-shot unguided anti-tank weapon. The solid rocket propulsion unit was developed in the newly-formed Rohm and Haas research laboratory at Redstone Arsenal in 1959, and the full system was designed by Paul V. Choate, Charles B. Weeks, Frank A. Spinale, et al. at the Hesse-Eastern Division of Norris Thermador. American production of the weapon began by Hesse-Eastern in 1963, and was terminated by 1983; currently it is produced by Nammo Raufoss AS in Norway and their subsidiary, Nammo Talley, Inc. in Arizona. In early 1963, the M72 LAW was adopted by the U.S. Army and U.S. Marine Corps as their primary individual infantry anti-tank weapon, replacing the M31 HEAT rifle grenade and the M20A1 "super bazooka" in the U.S. Army. It was subsequently adopted by the U.S. Air Force to serve in an anti-emplacement and anti-armor role in airbase defense. In the early 1980s, the M72 was slated to be replaced by the FGR-17 Viper. However, the Viper program was canceled by Congress and the M136 AT4 was adopted instead. At that time, its nearest equivalents were the Swedish Pskott m/68 (Miniman) and the French SARPAC. Background The increased importance of tanks and other armored vehicles in World War II caused a need for portable infantry weapons to deal with them. The first to be used (with limited success) were Molotov cocktails, flamethrowers, satchel charges, jury-rigged landmines, and specially designed magnetic hollow charges. All of these had to be used within a few meters of the target, which was difficult and dangerous. The U.S. Army introduced the bazooka, the first rocket-propelled grenade launcher. Despite early problems, it was a success and was copied by other countries. However, the bazooka had its drawbacks. Large and easily damaged, it required a well-trained two-man crew. Germany developed a one-man alternative, the Panzerfaust, having single-shot launchers that were cheap and requiring no special training. As a result, they were regularly issued to Volkssturm home guard regiments. They were very efficient against tanks during the last days of World War II. The M72 LAW is a combination of the two World War II weapons. The basic principle is a miniaturized bazooka, while its light weight and cheapness rival the Panzerfaust.
