In the early 1960s, when city crimes in the United States were increasing at an alarming rate, the U.S. police forces and the federal agency put together a military strategy system to fight against the rampaging criminals, the LAPD (Los Angeles Police Department) established the first special unit to combat highly armed criminals.
It was named S.W.A.T. (Special Weapons And Tactics) by LAPD commander Daryl F. Gates, and it has brought a new revolution to crime resistance.
In 1971, the SWAT team became a permanent force with a unified structure: small units comprised of 6 soldiers and middle sized groups comprised of 60 soldiers.
The SWAT has worked through the 1970s in suppressing armed criminals and with their help, was able to suppress major armed conflicts with zero or minimal civilian casualties.
