Swat

SWAT (Special Weapons And Tactics) is a term for law enforcement units which use specialized or military equipment and tactics in the United States. First created in the 1960s to handle riot control or violent confrontations with criminals, the number and usage of SWAT teams increased in the 1980s and 1990s during the War on Drugs and later in the aftermath of the September 11 attacks. In the United States as of 2005, SWAT teams were deployed 50,000 times every year, almost 80% of the time to serve search warrants, most often for narcotics. SWAT teams are increasingly equipped with military-type hardware and trained to deploy against threats of terrorism, for crowd control, and in situations beyond the capabilities of ordinary law enforcement, sometimes deemed "high-risk." Other countries have developed their own paramilitary police units (PPUs) that are also described as or compared to SWAT forces.

SWAT units are often equipped with specialized firearms including submachine guns, assault rifles, breaching shotguns, sniper rifles, riot control agents, and stun grenades. In addition, they may use specialized equipment including heavy body armor, ballistic shields, entry tools, armored vehicles, night vision devices, and motion detectors for covertly determining the positions of hostages or hostage takers, inside enclosed structures.

According to the Historical Dictionary of Law Enforcement, the term "SWAT" was used as an acronym for the "Special Weapons and Tactics" established as a 100-man specialized unit in 1964 by the Philadelphia Police Department in response to an alarming increase in bank robberies. The purpose of this unit was to react quickly and decisively to bank robberies while they were in progress, by utilizing a large number of specially trained officers who had at their disposal a great amount of firepower. The tactic worked and was later soon to resolve other types of incidents involving heavily-armed criminals.Los Angeles Police Department (LAPD) Inspector Daryl Gates has said that he first envisioned "SWAT" as an acronym for "Special Weapons Attack Team" in 1967, but later accepted "Special Weapons and Tactics" on the advice of his deputy chief, Edward M. Davis.
