M-72 Light Anti-tank Weapon
Weighing 2.37-kg (5.2 pounds) complete, the LAW was designed as a discardable one-man rocket launcher primarily for use as an anti-tank weapon. In Vietnam however, the LAW was used almost exclusively as a bunker buster or for attacking entrenched enemies.
When carried, the smooth-bore launcher tube was carried closed, and was watertight. In action, the end covers were opened by removing safety pins and the inner tube was telescoped outwards. This cocked the firing mechanism. Held over the shoulder, aimed by the simple sights, the weapon was fired by pressing the trigger button. The LAW Fired a 1-kg rocket to a maximum effective range of 300m.
The rocket motor was fully burnt out by the time it left the launcher and resulted in a large back-blast danger area behind the firer. Once fired the tube was discarded. Due to it’s low weight, a number of complete assemblies could be carried in a squad with each person capable of packing at least two if necessary.
