Non-lethal weapon

[9] The U.S. Congress and other governments agreed and began an organized development of non-lethal weapons to provide a range of options between talking and shooting.

Some non-lethal weapons may provide more effective riot control than firearms, truncheons or bayonets with less risk of loss of life or serious injury.

In 2001, the United States Marine Corps revealed its development of a less-than-lethal energy weapon called the Active Denial System, a focused high frequency microwave device said to be capable of heating all living matter in the target area rapidly and continuously for the duration of the beam, causing transient intolerable pain but no lasting damage.

[10] In 2004, author Jon Ronson cited an unclassified military report titled "Non-Lethal Weapons: Terms and References"[11][12] 21 acoustic weapons were listed, in various stages of development, including the Infrasound ("Very low-frequency sound which can travel long distances and easily penetrate most buildings and vehicles ... biophysical effects are projected to be: nausea, loss of bowels, disorientation, vomiting, potential internal organ damage or death may occur.

Other reasonably successful approaches included shotguns with lower-powered cartridges, "salt shells", using bean-bag rounds and ricocheting shots off of the ground.

In the 1980s the development of high-tensile plastics like Kevlar and Lexan revolutionized personal armor and shields, and led to new tactics for riot squads and other special-purpose teams.

In the 1980s and 1990s officers began deploying non-lethal personal sidearms such as pepper sprays, and eventually electroshock weapons such as tasers, which were developed for use by police and also found a market in self-defense by private citizens.

In the late 1990s and early 2000s (decade), police began to adopt a new pepper spray delivery system based on the equipment used in paintball.

Misplaced or ricocheting shots, pre-existing medical conditions, inadequate user training, repetitive applications and intentional misuse have been implicated in different cases where death has occurred.

More recently, high-velocity paintball guns are also used to launch less-lethal rounds, including the FN 303 launcher and PepperBall commercial products.

[citation needed] In 1972, stun grenades were used to capture the hijacked Sabena Flight 571, allowing the Israeli forces headed by Ehud Barak and including Benjamin Netanyahu to storm the plane and take it over within 10 minutes while capturing two terrorists and killing Ali Taha, the leader of the terrorist group and his aide, while rescuing all passengers (three were wounded, and one died of her injuries several days later).

It is a form of mist sprayed from a water cannon, which leaves a terrible odor of rot or sewage on whatever it touches, and does not wash off easily.

[27] The use of chemical weapons such as tear gas (CS) and pepper spray (OC) has come under increasing scrutiny and criticism due to studies showing serious long term side effects.

[citation needed][28] Journalist Rubén Salazar was killed in Los Angeles in 1970 by an errant CS gas canister during the Chicano riots.

The central nervous system effects, such as anesthesia and respiratory depression could have been reversed by an opioid antagonist such as naloxone, which is stocked by hospitals and most ambulances.

However, because the Russian authorities did not release any information regarding what type of agent was used, medical professionals were unaware that an opioid had been used during the rescue attempt and thus were unable to administer the antidote which could have saved most hostages.

[citation needed] Sticky foam was tried by the U.S. Marine Corps in the peacekeeping Operation United Shield in 1995 with some success, but as a result various complications in its field use were also discovered.

[35] They are known to have been in use since Roman times and may have been used earlier: the concept was familiar to the 4th century BC Greeks, who used rocks, brush, nets and trees placed in the path of enemy conveyances on land or ensnarement devices hidden under water to achieve the same result: stop the enemy or suspected hostile in his tracks for examination or to prevent or limit incursions.

[32] However, due to the difficulty of mass-producing them in the pre-modern age, they were rarely used except in the defense of limited areas or chokepoints, especially during sieges, where they were used to help seal breaches.

One type is a conductive energy device (CED), an electroshock gun popularly known by the brand name "Taser", which fires projectiles that administer the shock through a thin, flexible wire.

HSV Technologies, Inc. (named for its founders, Herr, Schlesinger and Vernon; not to be confused with Holden Special Vehicles), formerly of San Diego, California, USA, then Port Orchard, WA, designed a non-lethal device which was profiled in the 2002 TIME magazine article "Beyond the Rubber Bullet".

It involves the emission of an invisible laser pulse which, upon contact with the target, ablates the surface and creates a small amount of exploding plasma.

This produces a pressure wave designed to stun the target and knock them off their feet, and electromagnetic radiation that affects nerve cells causing a painful sensation.

[citation needed] United States Special Operations Command FY 2010 plans included starting developmental work on a counter UAV pulsed energy projectile.

[39] An active denial system (ADS) is a dish that projects electromagnetic radiation just powerful enough to penetrate human skin and make the victim feel as though they are on fire, although no physical damage is done.

[citation needed] The ADS is a non-lethal, directed-energy weapon developed by the US military,[40] designed for area denial, perimeter security and crowd control.

[44] Air Force Special Operations Command is experimenting with mounting an ADS on the AC-130J Ghostrider gunship to target threatening crowds or individuals on the ground.

[citation needed] The personnel halting and stimulation response rifle (PHASR) is a prototype non-lethal laser dazzler developed by the Air Force Research Laboratory's Directed Energy Directorate, U.S. Department of Defense.

[citation needed] Several nations developed blinding laser weapons and they were allegedly used during War in Donbass by Russia.

"[61] Safety and evaluation of the physical and psychological effects of the long-term or repetitive uses of the pain-inducing non-lethal weapons on humans have not been well understood or studied in any great details.
