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 {{cvt|66|mm|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,<ref>E. T. DeRieux et al. ''Final Report – Development of LAW Propulsion Unit'', R&H RARD, Technical Report No. S-12, December 1959</ref> 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 [[Company:Nammo|Nammo]] Raufoss AS in Norway and their subsidiary, Nammo Talley, Inc. in Arizona.<ref>[http://www.talleyds.com/Talley%20Nammo%20Test%20page/products/m72_products.htm "M72 products"] {{webarchive|url=https://web.archive.org/web/20150321040042/http://www.talleyds.com/Talley%20Nammo%20Test%20page/products/m72_products.htm |date=2015-03-21}}.

In early 1963, the M72 LAW was adopted by the U.S. Army and U.S. Marine Corps as their primary individual infantry [[Social:Anti-tank warfare|anti-tank]] weapon, replacing the [[Engineering:M31 HEAT rifle grenade|M31 HEAT rifle grenade]] and the [[Engineering:Bazooka#Rocket Launcher, M20A1 "super bazooka"|M20A1 "super bazooka"]] in the U.S. Army. It was subsequently adopted by the {{wipe|United States Air Force}} to serve in an anti-emplacement and anti-armor role in airbase defense.<ref>Mary T. Cagle "History of the TOW Missile System", page 10, U.S. Army, 1977.</ref><ref group=note>The U.S. Army partially replaced the super bazooka not only with the M72 LAW, but also the M67 recoilless rifle, and U.S. Marines kept the super bazooka in service until the late 1960s.{{citation needed|date=October 2021}}</ref>

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==
[[File:LAW-1961.jpg|upright|thumb|left|1961 LAW prototype, showing the rejected front sight that also served as the front cover]]
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 [[Engineering:Molotov cocktail|Molotov cocktail]]s, [[Physics:Flamethrower|flamethrower]]s, 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 [[Engineering:Bazooka|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.

==Description==
[[File:Licht anti-tankwapen (LAW M72) voor eenmalig gebruik (2086-067-006).jpg|thumb|left|The M72 rocket and launcher in cross-section.]]
[[File:Law ftbenning 1960 04.jpg|thumb|left|upright|M72 demonstration at Fort Benning, Georgia in the 1960s]]

The weapon consists of a [[Engineering:Rocket|rocket]] within a launcher consisting of two tubes, one inside the other. While closed, the outer assembly serves as a watertight container for the rocket and the percussion-cap 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 [[Engineering:Detent|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. It is a [[Engineering:Line of sight (missile)|line of sight weapon]] with a range around {{convert|200|m|ft|sp=us}}.<ref name=modeq/>

[[File:M72A2 LAW 1969.jpg|thumb|Packing crates are used to demonstrate the danger of the M72's back blast]]
When fired, the striker in the rear tube impacts a primer, which ignites a small amount of powder that "flashes" down a tube to the rear of the rocket and ignites the propellant in the rocket motor. The rocket motor burns completely before leaving the mouth of the launcher, producing a [[Engineering:Backblast area|backblast]] of gases around {{convert|1400|°F|°C|abbr=on}}. The rocket propels the {{cvt|66|mm|in}} 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. The early LAW warhead, developed from the [[Engineering:M31 HEAT rifle grenade|M31 HEAT rifle grenade]] warhead, uses a simple piezoelectric fuze system. On impact with the target, the front of the nose section is crushed, causing a microsecond electric current to be generated, which detonates a booster charge located in the base of the warhead, which sets off the main warhead charge. The force of the main charge forces the copper liner into a directional particle jet that, in relation to the size of the warhead, is capable of a massive penetration.

A unique mechanical set-back safety on the base of the detonator grounds the circuit until the missile has accelerated out of the tube. The acceleration causes the three disks in the safety mechanism to rotate 90° in succession, ungrounding the circuit; the circuit from the nose to the base of the detonator is then completed when the piezoelectric crystal is crushed on impact.

The weapon can be fired from inside buildings as long as the structure is at least {{cvt|12|by|15|ft|m|order=flip}} in size, which is about {{convert|50|m3|ft3|sp=us}} in volume, and has sufficient ventilation.<ref>{{cite web |title=SQUAD WEAPONS B2E2657 Student Handout |url=https://www.trngcmd.marines.mil/Portals/207/Docs/TBS/B2E2657%20Squad%20Weapons.pdf |website=trngcmd.marines.mil |publisher=UNITED STATES MARINE CORPS}}</ref><ref>{{cite web |title=FM 3–23.25 SHOULDER-LAUNCHED MUNITIONS |url=https://www.bits.de/NRANEU/others/amd-us-archive/fm3-23.25%2806%29.pdf |website=bits.de |publisher=DEPARTMENT OF THE ARMY}}</ref> The Department of the Army previously rated the weapon as safe to fire from enclosure, but this rating was removed in 2010 after the introduction of the safer AT4 CS.<ref>{{cite web |title=TM 3–23.25(FM 3–23.25) Shoulder-Launched Munitions |url=https://armypubs.army.mil/epubs/DR_pubs/DR_a/pdf/web/tm3_23x25.pdf |website=armypubs.army.mil |publisher=Department of the Army}}</ref> However, some modern variants of the LAW are specifically designed with fire-from-enclosure (FFE) capability.<ref>{{cite web |last1=Gonzales |first1=Matt |title=MARINE CORPS RELEASES SOLICITATION FOR ROCKET SYSTEM |url=https://www.marcorsyscom.marines.mil/News/News-Article-Display/Article/2297371/marine-corps-releases-solicitation-for-rocket-system/ |website=marcorsyscom.marines.mil |publisher=MCSC Office of Public Affairs and Communication}}</ref>

In late 2021, Nammo unveiled the concept of a multi-[[Engineering:Helicopter rotor|rotor]] [[Engineering:Unmanned aerial vehicle|unmanned aerial vehicle]] (UAV) equipped with a LAW. The tube is mounted facing downward, enabling the drone operator to fire on tanks and armored vehicles from a top attack position while remaining {{cvt|3|to|4|km|mi}} away.<ref>{{cite web |last1=Dalløkken |first1=Per Erlien |title=Luftbåren M72: Nammo monterer raketter på drone – kan være et billig og effektivt panservernvåpen |url=https://www.tu.no/artikler/luftbaren-m72-nammo-monterer-raketter-pa-drone-kan-vaere-et-billig-og-effektivt-panservernvapen/514386 |website=Tu.no |publisher=Teknisk Ukeblad |language=no |date=29 October 2021}}</ref>

==Ammunition==
[[File:M72 1.gif|right|thumb|An M72 LAW's rocket]]

M72 LAWs were issued as prepackaged rounds of ammunition. Improvements to the launcher and differences in the ammunition were differentiated by a single designation. The original M72 warhead penetrated {{cvt|30|cm|in}} of armor.<ref>{{cite web |title=FM 7-7 |url=http://www.bits.de/NRANEU/others/amd-us-archive/FM7-7%2885%29.pdf |website=www.bits.de |access-date=10 November 2018 |date=March 1985 |archive-url=https://web.archive.org/web/20180630081244/http://www.bits.de/NRANEU/others/amd-us-archive/FM7-7%2885%29.pdf |archive-date=30 June 2018 |url-status=live }}</ref><ref>{{cite web |title=LIGHT ANTIARMOR WEAPONS |url=http://pdf.textfiles.com/manuals/MILITARY/united_states_army_fm_3-23x25%20-%2030_august_2001.pdf |publisher=DEPARTMENT OF THE ARMY |access-date=10 November 2018 |date=30 August 2001 |archive-url=https://web.archive.org/web/20130124063044/http://pdf.textfiles.com/manuals/MILITARY/united_states_army_fm_3-23x25%20-%2030_august_2001.pdf |archive-date=24 January 2013 |url-status=live }}</ref>

A training variant of the M72 LAW, designated ''M190'', also exists. This weapon is reloadable and uses the {{cvt|35|mm|in}} ''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 fires {{cvt|9|mm|in}} tracer rounds.

The US Army tested other 66&nbsp;mm rockets based on the ''M54'' rocket motor used for the M72. The ''M74 TPA'' (thickened pyrophoric agent) had an incendiary warhead filled with TEA ([[Chemistry:Triethylaluminium|triethylaluminum]]); this was used in the M202A1 FLASH (flame assault shoulder weapon) four-tube launcher. The ''XM96 RCR'' (riot control rocket) had a [[Chemistry:CS gas|CS gas]]-filled warhead for crowd control and was also intended for use with the M202, though the rocket never entered service.

===Finland===
The M72 LAW is 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). In accordance with the weapon's known limitations, a pair of "tank-buster" troops crawl to a firing position around {{convert|50|to|150|m|ft|sp=us}} away from the target, bringing with them four to six LAWs, which are then used in rapid succession until the target is destroyed or incapacitated. Due to its low penetration capability, it is used mostly against lightly-armored targets. The M72 is the most common anti-tank weapon in the Finnish Army.{{Citation needed|date=April 2011}} Finland has recently upgraded its stocks to the M72 EC LAW Mk.I version.

===Taiwan===
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 M136 (AT4) anti-tank weapons.{{Citation needed|date=April 2008}} The weapon was later reverse-engineered into the "Type 1 66&nbsp;mm anti-tank rocket" but is more-popularly nicknamed as the "Type 66 rocket" due to its caliber.

===Turkey===
The Turkish Army uses a locally built version by Makina ve Kimya Endustrisi Kurumu, called HAR-66 (''Hafif Antitank Roketi'', 'light antitank rocket'), which has the performance and characteristics of a mix of an M72A2 and an A3.

During the Vietnam and post-Vietnam periods, all issued LAWs were recalled after instances of the warhead exploding in flight, sometimes injuring the operator. After safety improvements, part of the training and firing drills included the requirement to ensure that the words "w/coupler" were included in the text description stenciled on the launcher, which indicated that the launcher had the required safety modifications.{{Citation needed|date=January 2009}}<ref group=note>Some reports state these instances were caused by misfires due to water in the flash tube and by unproven rumors of sabotage at the manufacturing plant during the Vietnam War{{citation needed|date=October 2021}}</ref>

With the failure of the M72's intended replacement, the Viper, in late 1982 Congress ordered the US Army to test off-the-shelf light antitank weapons and report back by the end of 1983. In partnership with Raufoss AS, Talley Defense offered the M72E5, which offered increased range, penetration and better sights; this was tested along with five other light anti-armor weapons in 1983. Despite the improvements that the M72E5 offered, the AT4 was chosen to replace the M72.<ref>D. Kyle, ''Armed Forces Journal International'', November 1983, "Viper Dead, Army Picks AT-4 Antitank Missile", page 21</ref><ref group=note>Various reports in 1983 stated that during the congressionally-mandated tests the first M72E5 tested had an accuracy problem, because its larger-diameter rocket motor interfered with the deployment of all the stabilizing fins after leaving the launcher. The manufacturers have since made modifications that have solved that problem.{{citation needed|date=October 2021}}</ref>

Although generally thought of as a Vietnam War–era weapon that has been superseded by the more-powerful AT4, the M72 LAW found new popularity in the operations by the U.S. Army, the U.S. Marine Corps, and Canadian Army in Iraq and Afghanistan. The lower cost and lighter weight of the LAW, combined with a scarcity of modern heavy armored targets and the need for an individual assault weapon versus an individual anti-armor weapon, made it ideal for the type of urban combat seen in Iraq and mountain warfare seen in Afghanistan. In addition, a soldier can carry two LAWs on a mission as opposed to a single AT4.<ref>{{cite web |url=http://www.defenseindustrydaily.com/marines-fought-the-law-and-the-law-won-0151 |title=Marines Fought the LAW, and the LAW Won |publisher=Defenseindustrydaily.com |date=2005-03-10 |access-date=2013-01-01 |archive-url=https://web.archive.org/web/20130125205134/http://www.defenseindustrydaily.com/marines-fought-the-law-and-the-law-won-0151/ |archive-date=2013-01-25 |url-status=live }}</ref>
