Description
The weapon consists of a rocket packed inside of a launcher made up of two tubes, one inside the other. A rocket or rocket vehicle is a Missile, Aircraft or other Vehicle which obtains Thrust by the reaction of the While closed, the outer assembly acts as a watertight container for the rocket and the percussion cap-type firing mechanism that activates the rocket. The outer tube contains the trigger, the arming handle, front and rear sights, and the rear cover. The inner tube contains the channel assembly which houses the firing pin assembly, including the detent lever. When extended, the inner tube telescopes outward toward the rear, guided by the channel assembly which rides in an alignment slot in the outer tube's trigger housing assembly. This causes the detent lever to move under the trigger assembly in the outer tube, both locking the inner tube in the extended position and cocking the weapon. Once armed, the weapon is no longer watertight even if the launcher is collapsed into its original configuration.
When fired, the propellant in the rocket motor completely combusts before leaving the tip of the launcher, producing gases around 1,400 °F (760 °C). The rocket propels the 66 mm warhead forward without significant recoil. As the warhead emerges from the launcher, six fins spring out from the base of the rocket tube, stabilizing the warhead's flight.
Once fired the launcher is no longer useful and may be discarded. Due to the single use nature of the weapon, it was issued as a round of ammunition by the Canadian Army and the United States Army. Ammunition, often referred to as ammo, is a generic term derived from the French language la munition which Land Force Command ( LFC) is responsible for army operations within the Canadian Forces.
Ammunition
The M72 LAW was issued as a prepackaged round of ammunition. Improvements to the launcher and differences in the ammunition were differentiated by a single designation. The most common M72 LAWs came prepacked with a rocket containing a 66 mm HEAT warhead which is attached to the inside of the launcher by the igniter. The warhead is activated by an impact sense sensor in the nose cone which is connected to the fuse. The fuse then detonates a booster which sets off the main charge. The force of the main charge forces the copper liner into a directional jet that is capable of penetrating up to 0. 3 m (1 ft) of steel plate, 0.

A training variant of the M72 LAW, designated the M190, also exists. This weapon is reloadable and uses the 35 mm M73 training rocket. A subcaliber training device that uses a special tracer cartridge also exists for the M72. A training variant used by the Finnish armed forces fire 9mm tracer rounds. The Finnish Defence Forces is responsible for defence of Finland.
The US Army tested other 66 mm rockets based on the M54 rocket motor used for the M72, including the M74 and XM96. These rockets were used with the XM191 and M202 Flash 4 tube launchers.
Service history
Although generally thought of as a Vietnam War era weapon which has been superseded by more powerful and sophisticated designs such as the SMAW and AT4, the M72 LAW has found a new lease of life in the ongoing (2006) operations in Iraq by the US Army and Afghanistan by the Canadian Army. The Vietnam War, also known as the Second Indochina War, or the Vietnam Conflict, occurred in Vietnam, Laos and Cambodia The Shoulder-launched Multipurpose Assault Weapon (SMAW is a shoulder-launched rocket weapon based on the Israeli B-300, with the primary function of being a The AT4 (or AT-4 an alpha-phonetic word play on the weapon's Caliber of 84 mm is a portable one-shot Anti-tank Weapon built in Sweden For a topic outline on this subject see List of basic Iraq topics. Afghanistan /æfˈgænɪstæn/ officially the Islamic Republic of Afghanistan ( Pashto: د افغانستان اسلامي جمهوریت, The low cost and light weight of the LAW, combined with a proliferation of lightly-armored targets, make it ideal for the type of urban combat seen in Iraq and Afghanistan. [1]
The M72 LAW is also extensively used in the Finnish Army (some 70,000 pieces), where it is known under the designations 66 KES 75 (M72A2, no longer in service) and 66 KES 88 (M72A5). The Finnish Army ( Finnish: Maavoimat, Swedish: Armén) is the land forces branch of the Finnish Defence Forces The British Army used the Norwegian built version of the M72 under the designation "Rocket 66mm HEAT L1A1" which was replaced by LAW 80. The British Army is the land armed forces branch of the British Armed Forces. The LAW 80 (Light Anti-armour Weapon 80 sometimes erroneously referred to as LAW 94, is a man-portable one-shot disposable Anti-tank weapon used by the
The Turkish Army uses a Turkish built version by Makina ve Kimya Endustrisi Kurumu, called HAR-66, which has the performance and characteristics of a mix of M72A2 and A3. The Turkish Army ( Turkish: Türk Kara Kuvvetleri) is a branch of the Turkish Armed Forces. Turkey (Türkiye known officially as the Republic of Turkey ( is a Eurasian Country that stretches The Mechanical and Chemical Industry Corporation (Makina ve Kimya Endüstrisi Kurumu or MKEK established in 1950 is a reorganization of government-controlled group of factories in Turkey also indigeneously developed an anti-personnel warhead version of HAR-66 and called it "Eşek Arısı".
The Australian Army uses the M72A6 as an anti-building and secondary anti-armour weapon. It is carried by regular riflemen (including on operations in Iraq), while the heavier 84mm Carl Gustaf and Javelin are generally equipped by dedicated anti-armour troops. The Carl Gustav (also Carl-Gustaf) is the common name for the 84 mm man-portable multi-role Recoilless rifle produced by Saab Bofors Dynamics (formerly The FGM-148 Javelin is an American -made man-portable Anti-tank guided missile.
The Republic of China Army (Taiwan) uses the M72 as a secondary anti-armor weapon. It is used primarily as a backup to the Javelin and the M136 (AT4) anti-tank weapons.
Surplus demand
- Expended LAW tubes may be found on the US military surplus and gun show market, and purchased by militaria collectors. Military surplus are goods usually Matériel, that are sold at public Auction when no longer needed by the Military. Militaria are artifacts or Replicas of Military, Police, etc collected for their Historical significance
Demonstration
- A fairly accessible demonstration of the use of this rocket (including a good reason for not standing behind one when it goes off) is featured in the Clint Eastwood film The Enforcer. The Enforcer is the 1976 third film in the Dirty Harry series.
