Riot control in the context of Less-lethal weapon

Riot police are police who are organized, deployed, trained or equipped to confront crowds, protests or riots.

Riot police may be regular police officers who act in the role of riot police in particular situations, or they may be separate units organized within or in parallel to regular police forces. Riot police are used in a variety of different situations and purposes. They may be employed to control riots as their name suggests, to disperse or control crowds, to maintain public order or discourage criminality, or to protect people or property. The militarization of modern police has brought militaristic riot gear and new technologies that allow for their duties to expand above normal police duties.

The militarization of police (paramilitarization of police in some media) is the use of military equipment and tactics by law enforcement officers. This includes the use of armored personnel carriers (APCs), assault rifles, submachine guns, flashbang grenades, sniper rifles, and SWAT (special weapons and tactics) teams. The militarization of law enforcement is also associated with intelligence agency–style information gathering aimed at the public and political activists and with a more aggressive style of law enforcement. Criminal justice professor Peter Kraska has defined militarization of police as "the process whereby civilian police increasingly draw from, and pattern themselves around, the tenets of militarism and the military model".

Observers have noted the militarizing of the policing of protests. Since the 1970s, riot police have fired at protesters using guns with rubber bullets or plastic bullets. Tear gas, which was developed by the United States Army for riot control in 1919, is still widely used against protesters. The use of tear gas in warfare is prohibited by various international treaties that most states have signed; however, its law enforcement or military use for domestic or non-combat situations is permitted.

Crowd control is a public security practice in which large crowds are managed in order to prevent the outbreak of crowd crushes, affray, fights involving drunk and disorderly people or riots. Crowd crushes in particular can cause many hundreds of fatalities. Effective crowd management is about managing expected and unexpected crowd occurrences. Crowd control can involve privately hired security guards as well as police officers. Crowd control is often used at large, public gatherings like street fairs, music festivals, stadiums and public demonstrations. At some events, security guards and police use metal detectors and sniffer dogs to prevent weapons and drugs being brought into a venue.

A stun grenade, also known as a flash grenade, flashbang, thunderflash, or sound bomb, is a non-lethal explosive device used to temporarily disorient an enemy's senses. Upon detonation, a stun grenade produces a blinding flash of light and an extremely loud "bang". They are often used in close-quarters combat, door breaching, and riot control, typically to stun enemies or distract them.

Originally developed to simulate explosions during military training, stun grenades were first used by the British Army Special Air Service's counterterrorist wing in the late 1970s, and have been used by police and military forces worldwide since.

Rubber bullets (also called rubber baton rounds) are a type of baton round. Despite the name, rubber bullets typically have either a metal core with a rubber coating, or are a homogeneous admixture with rubber being a minority component. Although they are considered a less lethal alternative to metal projectiles, rubber bullets can still cause fatal injuries as well as other serious injuries such as blindness or other permanent disabilities.

Like other similar projectiles made from plastic, wax, and wood, rubber bullets may be used for short range practice and animal control, but are most commonly used in riot control and to disperse protests.

Plastic bullet can refer to:

• Plastic baton round: a large, blunt, low-velocity projectile fired from a specialized gun, intended as a less-lethal weapon for riot control and an alternative to rubber bullets.
• Plastic bullet: a conventionally sized and shaped bullet made from a composite material including plastic, fired from a conventional rifle and capable of penetrating human tissue, intended as a less lethal weapon for riot control.

• Plastic bullet (target shooting): a blunt, lightweight handgun bullet intended for short-range target practice, not intended for use as a weapon.

Both types of plastic bullet intended for riot control have caused deaths.

Tear gas, also known as a lachrymatory agent or lachrymator (from Latin lacrima 'tear'), sometimes colloquially known as "mace" after the early commercial self-defense spray, is a chemical weapon that stimulates the nerves of the lacrimal gland in the eye to produce tears. In addition, it can cause severe eye and respiratory pain, skin irritation, bleeding, and blindness. Common lachrymators both currently and formerly used as tear gas include pepper spray (OC gas), PAVA spray (nonivamide), CS gas, CR gas, CN gas (phenacyl chloride), bromoacetone, xylyl bromide, chloropicrin (PS gas) and Mace (a branded mixture).

While lachrymatory agents are commonly deployed for riot control by law enforcement and military personnel, its use in warfare is prohibited by various international treaties. During World War I, increasingly toxic and deadly lachrymatory agents were used.

In current usage, a riot gun or less-lethal launcher is a type of firearm used to fire "non-lethal" or "less-lethal" ammunition for the purpose of suppressing riots or apprehending suspects with minimal harm or risk. Less-lethal launchers may be special purpose firearms designed for riot control use, or standard firearms, usually shotguns and grenade launchers, adapted for riot control use with appropriate ammunition. The ammunition is most commonly found in 12 gauge (18.5 mm/.729 inch) shotguns and 37mm (1.46 inch) or 40 mm (1.57 inch) grenade launchers.

In the United States, the term riot gun more commonly refers to a riot shotgun.

The Separate Corps of Gendarmes (Russian: Отдельный корпус жандармов) was the uniformed security police of the Imperial Russian Army in the Russian Empire during the 19th and early 20th centuries. Its main responsibilities were law enforcement and state security.

The responsibilities of the Gendarmes also included the execution of court orders, pursuit of fugitives, riot control, and detainment of "unusual" criminals. Gendarmes could also be assigned to assist local police and officials.

Non-lethal weapons, also called nonlethal weapons, less-lethal weapons, less-than-lethal weapons, non-deadly weapons, compliance weapons, or pain-inducing weapons are weapons intended to be less likely to kill a living target than conventional weapons such as knives and firearms with metal-projectile ammunition. It is often understood that unintended or incidental casualties are risked wherever force is applied; however, non-lethal weapons minimise the risk of casualties (e.g. serious/permanent injuries or death) as much as possible. Non-lethal weapons are used in policing and combat situations to limit the escalation of conflict where employment of lethal force is prohibited or undesirable, where rules of engagement require minimum casualties, or where policy restricts the use of conventional force. However, these weapons occasionally cause serious injuries or death due to allergic reactions, improper use and/or other factors; for this reason the term "less-lethal" has been preferred by some organizations as it describes the risks of death more accurately than the term "non-lethal", which some have argued is a misnomer.

Non-lethal weapons may be used by conventional military in a range of missions across the force continuum. They may also be used by military police, by United Nations forces, and by occupation forces for peacekeeping and stability operations. Non-lethal weapons may also be used to channelize a battlefield, control the movement of civilian populations, or to limit civilian access to restricted areas (as they were utilized by the USMC's 1st Marine Expeditionary Force in Somalia in 1995). Similar weapons, tactics, techniques and procedures are employed by police forces domestically in riot control, prisoner control, crowd control, refugee control, and self-defense, where the terminology of "less-than-lethal" is often used.

The People's Armed Police Force is a Chinese gendarmerie organization primarily responsible for internal security, riot control, counter-terrorism, disaster response, law enforcement and maritime rights protection as well as providing support to the People's Liberation Army (PLA) during wartime.

Unlike the civilian People's Police, the PAP is a specialized paramilitary force reporting directly to the Central Military Commission (CMC) of the Chinese Communist Party (CCP). PAP officers and soldiers wear dark olive green uniforms, different from pine green uniforms of the People's Liberation Army Ground Force (PLAGF) or the light blue and black uniforms of the People's Police. Additionally, People's Armed Police police officers are active duty service members and receive veteran's benefits.

Operation Banner was the operational name for the British Armed Forces' operation in Northern Ireland from 1969 to 2007, as part of the Troubles. It was the longest continuous deployment in British military history. The British Army was initially deployed, at the request of the unionist government of Northern Ireland, in response to the August 1969 riots. Its role was to support the Royal Ulster Constabulary (RUC) and to assert the authority of the British government in Northern Ireland. This involved counter-insurgency and supporting the police in carrying out internal security duties such as guarding key points, mounting checkpoints and patrols, carrying out raids and searches, riot control and bomb disposal. More than 300,000 soldiers served in Operation Banner. At the peak of the operation in the 1970s, about 21,000 British troops were deployed, most of them from Great Britain. As part of the operation, a new locally-recruited regiment was also formed: the Ulster Defence Regiment (UDR).

The Provisional Irish Republican Army (IRA) waged a guerrilla campaign against the British military from 1970 to 1997. Catholics welcomed the troops when they first arrived, because they saw the RUC as sectarian, but Catholic hostility to the British military's deployment grew after incidents such as the Falls Curfew (1970), Operation Demetrius (1971) and Bloody Sunday (1972). In their efforts to defeat the IRA, there were incidents of collusion between British soldiers and Ulster loyalist paramilitaries. From the late 1970s the British government adopted a policy of "Ulsterisation", which meant giving a greater role to local forces: the UDR and RUC. After the Good Friday Agreement in 1998, the operation was gradually scaled down, most military facilities were removed and the vast majority of British troops were withdrawn.

The 4th Carabinieri Mounted Regiment (Italian: 4° Reggimento Carabinieri a Cavallo) is an Italian Carabinieri mounted police unit of the 1st Carabinieri Mobile Brigade. The regiment is tasked with riot control and rural patrol. It was formed on 1 April 1963 by merging smaller existing mounted units of the Carabinieri.

A Colonel commands the Regiment, which is located at the barracks "Tor di Quinto" in Rome. The Carabinieri Regiment is popular for their famous horse carousel that reaches reenacts the Carabinieri's charge at the Battle of Pastrengo.

A water cannon is a device that shoots a high-velocity stream of water. Typically, a water cannon can deliver a large volume of water, often over dozens of meters. They are used in firefighting, large vehicle washing, riot control, and mining. Most water cannons fall under the category of a fire monitor.

The Texas Ranger Division, also known as the Texas Rangers and nicknamed the Diablos Tejanos (Spanish for 'Texan Devils'), is an investigative law enforcement agency with statewide jurisdiction in the U.S. state of Texas, based in the capital city Austin. The Texas Rangers have investigated crimes ranging from murder to political corruption, acted in riot control and as detectives, protected the governor of Texas, tracked down fugitives, served as a security force at important state locations, including the Alamo, and functioned as a paramilitary force at the service of both the Republic (1836–1846) and the State of Texas. Today they also conduct cybercrime investigations, cold case reviews, public corruption probes, and provide tactical support in major emergencies.

The Texas Rangers were unofficially created by Stephen F. Austin in a call-to-arms written in 1823. After a decade, on August 10, 1835, Daniel Parker introduced a resolution to the Permanent Council creating a body of rangers to protect the Mexican border. The unit was dissolved by the federal authorities after the Civil War during the Reconstruction Era but was quickly reformed upon the reinstitution of home government. Since 1935, the organization has been a division of the Texas Department of Public Safety (TxDPS); it fulfills the role of Texas' state bureau of investigation. As of 2019, there are 166 commissioned members of the Ranger force.

The Compagnies républicaines de sécurité (CRS; French: [kɔ̃paɲi ʁepyblikɛn də sekyʁite], Republican Security Corps) are the general reserve of the French National Police. They are primarily involved in general security missions, but the task for which they are best known is crowd and riot control. The DCCRS has seven units: in Paris, Lille, Rennes, Bordeaux, Marseille, Lyon and Metz.

There are 60 "general service" CRS companies, specialized in public order and crowd control; nine "motorway" companies (French: Compagnies autoroutières) specialized in highway patrol in urban areas; and six "zonal" motorcycle units (one per Defense zone.) Two additional companies and several mountain detachments administratively attached to local companies specialize in Mountain Rescue. One company (CRS n°1) specializes in VIP escort. The National Police band is also a CRS unit.

A flying wedge (also called flying V or wedge formation, or simply wedge) is a configuration created from a body moving forward in a triangular formation. This V-shaped arrangement began as a successful military strategy in ancient times when infantry units would move forward in wedge formations to smash through an enemy's lines. This principle was later used by Medieval European armies, as well as modern armed forces, which have adapted the V-shaped wedge for armored assault.

In modern times the effectiveness of flying wedge means it is still employed by civilian police services for riot control. It has also been used in some sports, although the use of wedges is sometimes banned due to the danger it poses to defenders.

The Civil Armed Forces (CAF) are a group of nine paramilitary and gendarmerie organisations, separate and distinct from the regular Pakistan Armed Forces. They are responsible for maintaining internal security, helping law enforcement agencies, border control, counter-insurgency and counter-terrorism, riot control, and anti-smuggling under the Ministry of Interior. They frequently operate alongside the Pakistani military in response to natural disasters. During times of war they can have their command transferred to the Ministry of Defence, and effectively combined to form a reserve force for the Pakistani military.
