The M72 consists of a disposable launcher that fires an unguided 66mm solid-fuel rocket. The basic concept is essentially an arithmetic mean between the American bazooka and the German WWII-vintage Panzerfaust. The light anti-armor weapon saw a great deal of use in the Vietnam War and has been improved multiple times over the years. The latest M72A7 weighs 7.9 pounds and has a maximum effective range of 220 meters. The point-initiated, base-detonated round travels at 480 feet per second. A mechanical setback feature prevents the warhead from detonating unless it has been fired.
The LAW consists of a single consumable round of ammunition carried within a pair of nested telescoping tubes. The internal tube is aluminum, while the outside sort is fiberglass. When collapsed, the LAW is waterproof and 25” long. Once extended and ready to fire, the M72 is 35” long. The weapon’s minimum arming range is ten meters. The front sight is graduated in 25-meter increments, and the rear peep sight automatically adjusts itself for ambient temperature.
