SWAT

SWAT is a commonly-used proper name for law enforcement units, which use military-style light weapons and specialized tactics in high-risk operations that fall outside of the capabilities of regular, uniformed police. The phrase is an acronym which stands for Special Weapons And Tactics. "SWAT" is commonly-used internationally, as a colloquial, generic term for these units.

Their duties include: confronting heavily-armed criminals; performing hostage rescue and counter-terrorism operations; high risk arrests; and entering armored or barricaded buildings. Such units are often equipped with specialized firearms including submachine guns, assault rifles, breaching shotguns, sniper rifles, riot control agents, and stun grenades. They have specialized equipment including heavy body armor, ballistic shields, entry tools, armored vehicles, advanced night vision optics, and motion detectors for covertly determining the positions of hostages or hostage takers, inside enclosed structures.
