A SWAT team is a group of highly trained police officers who deal with very dangerous criminals. SWAT is an acronym that means Special Weapons And Tactics. SWAT officers carry weapons of higher caliber than most police officers do, such as machine guns, shotguns, and sniper rifles. Usually, police departments use SWAT teams to catch people who sell illegal drugs or try to hold people hostage. They also respond to serious crimes like bank robberies when normal police officers can not control the robbers.
The SWAT teams are usually called to deal with hostage situations. They plan the entry into the building where the hostages are being held carefully. They look closely at all building entrances to choose the best option. They make use of equipment such as rappelling ropes, nightvision goggles, thermalvision goggles, a tactical shield, flashbang and smoke grenades, snake cameras (small cameras that fit under doors and into very small holes), among others.
