貫穿20公分車輛裝甲，60公分強化混凝土，1.8公尺土壤，美國陸軍及海軍陸戰隊，主要的單兵反戰車武器，M72 LAW（輕型反戰車/裝甲武器）

M72 LAW（輕型反戰車武器Light Anti-Tank Weapon、或稱輕型反裝甲武器Light Anti-Armor Weapon），簡稱LAW或LAWS（輕型反戰車武器系統）是一種由美國黑森東方公司於1958年開始研製的66公釐拋棄式火箭筒，當時設計者為Paul V. Choate、Charles B. Weeks以及Frank A. Spinale et al，實際負責生產的是挪威的Nammo Raufoss AS公司。該武器於1958年開始研發，在1963年初被美國陸軍及海軍陸戰隊採用，並取代M31反戰車槍榴彈和M20A1超級巴祖卡，成為主要的單兵反戰車武器。在1980年代早期，美國軍方原本有意以FGR-17 Viper取代M72，但這個計畫因最後陸軍決議而取消。同時期與M72反裝甲火箭結構近似的武器有瑞典製造的Pskott m/68（Miniman），與法國所生產的SARPAC。
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 66 mm (2.6 in) 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, then the full system was designed by Paul V. Choate, Charles B. Weeks, Frank A. Spinale, et al. at the Hesse-Eastern Division of Norris Thermadore. 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/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.
