Assault rifle in the context of "AKM"

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.

The M16 rifle (officially designated Rifle, Caliber 5.56 mm, M16) is a family of assault rifles adapted from the ArmaLite AR-15 rifle for the United States military. The original M16 rifle was a 5.56×45mm automatic rifle with a 20-round magazine.

In 1964, the XM16E1 entered US military service as the M16 and in the following year was deployed for jungle warfare operations during the Vietnam War. In 1969, the M16A1 replaced the M14 rifle to become the US military's standard service rifle. The M16A1 incorporated numerous modifications including a bolt-assist ("forward-assist"), chrome-plated bore, protective reinforcement around the magazine release, and revised flash hider.

The AK-47, officially known as the Avtomat Kalashnikova (Russian: Автомат Калашникова, lit. 'Kalashnikov's automatic [rifle]'; also known as the Kalashnikov or just AK), is an assault rifle that is chambered for the 7.62×39mm cartridge. Developed in the Soviet Union by Russian small-arms designer Mikhail Kalashnikov, it is the originating firearm of the Kalashnikov (or "AK") family of rifles. After more than seven decades since its creation, the AK-47 model and its variants remain one of the most popular and widely used firearms in the world.

Design work on the AK-47 began in 1945. It was presented for official military trials in 1947, and, in 1948, the fixed-stock version was introduced into active service for selected units of the Soviet Army. In early 1949, the AK was officially accepted by the Soviet Armed Forces and used by the majority of the member states of the Warsaw Pact.

A battle rifle is a service rifle chambered to fire a fully powered cartridge.

The term "battle rifle" is a retronym created largely out of a need to differentiate automatic rifles chambered for fully powered cartridges from automatic rifles chambered for intermediate cartridges, which were later categorized as assault rifles. Battle rifles were most prominent from the 1940s to the 1970s, when they were used as service rifles. While modern battle rifles largely resemble modern assault rifle designs, which replaced battle rifles in most roles, the term may also describe older military full-power semi-automatic rifles such as the M1 Garand, SVT-40, Gewehr 41, Gewehr 43, Type 4, FN Model 1949, and MAS-49.

A service rifle (or standard-issue rifle) is a rifle a military issues to its regular infantry. In modern militaries, this is generally a versatile, rugged, and reliable assault rifle or battle rifle, suitable for use in nearly all environments and is effective in most combat situations. Almost all modern militaries are issued service pistols as sidearms to accompany their service rifles. The term can also be used to describe weapons issued by non-military forces, such as law enforcement or paramilitaries.

If the issued weapon is not a rifle or carbine, but instead a different type of firearm intended to serve in a specialized role such as a combat shotgun, submachine gun, or light machine gun, it is called a service firearm or service weapon.

The Heckler & Koch G36 (German: Gewehr 36) is an assault rifle designed in the early 1990s by German weapons manufacturer Heckler & Koch. It is chambered in 5.56×45mm NATO, and replaced the heavier G3 battle rifle chambered in 7.62×51mm. The G36 was accepted into service with the Bundeswehr in 1997. Since then, it has been a popular export, and has seen active service in military and police units in several countries, including Germany, Spain, and the United Kingdom. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine.

In 2012, the G36 was found to suffer from significant accuracy issues due to thermal expansion of the barrel, prompting a search for a replacement. In 2017, the Bundeswehr launched the System Sturmgewehr Bundeswehr, a program designed to field a replacement for the G36. The weapons put forth were the Heckler & Koch HK416, Heckler & Koch HK433, and the Haenel MK 556. The G95A1 and G95KA1, both variants of the HK416, were selected in 2022.

The Heckler & Koch HK33 is a 5.56mm assault rifle developed in the 1960s by West German armament manufacturer Heckler & Koch GmbH (H&K), primarily for export.

Building on the success of their G3 design, the company developed a family of small arms (all using the G3 operating principle and basic design concept) consisting of four types of firearms: the first type, chambered in 7.62×51mm NATO; the second, using the Soviet 7.62×39mm M43 round; the third, chambered in .223 Remington and 5.56×45mm NATO; and the fourth type, chambered for the 9×19mm Parabellum pistol cartridge. Commercially the HK33 was a successful design but it did not sell as well as the G3.

The Heckler & Koch G41 is a German 5.56×45mm NATO assault rifle introduced in 1981 and produced in limited quantities by Heckler & Koch. It was designed to replace the 7.62×51mm NATO chambered Heckler & Koch G3 and the G3 based .223 Remington/5.56×45mm and later 5.56×45mm NATO chambered Heckler & Koch HK33 service rifles providing a more modern weapon compatible with then recently introduced NATO standards. It can use both the then new STANAG 4172 compliant 5.56×45mm NATO SS109, SS110, and SS111 ammunition and older .223 Remington/5.56×45mm M193 ammunition and was the last Heckler & Koch service rifle designed around the roller-delayed blowback mechanism.

Commercially the G41 was not as successful as the preceding Heckler & Koch service rifle designs with a similar operating mechanism. It was rejected by various military trial programmes and it never won a major military production contract. Assembly of the G41 has been discontinued by Heckler & Koch; however, production rights to the rifle were acquired by the Italian arms manufacturer Luigi Franchi.

The AK-74 (Russian: Автомат Калашникова образца 1974 года, tr. Avtomat Kalashnikova obraztsa 1974 goda, lit. 'Kalashnikov assault rifle model 1974') is an assault rifle designed by small arms designer Mikhail Kalashnikov in 1974 as a successor to the AKM. While primarily associated with the Soviet Union, it has been used by many countries since the 1970s. It is chambered for the 5.45×39mm cartridge, which replaced the 7.62×39mm cartridge of Kalashnikov's earlier automatic weapons for the Soviet Armed Forces.

The rifle first saw service with Soviet forces in the Soviet–Afghan War from 1979. The head of the Afghan bureau of the Inter-Services Intelligence (ISI), the intelligence agency of Pakistan, claimed that the American Central Intelligence Agency (CIA) paid $5,000 for the first AK-74 captured by the Afghan mujahideen during the war.
