2. flashbang
(Grenade, hand, stun). a less lethal grenade used by US police, as well as special forces the world over. Typically such grenades deliver 9 ear splittingly loud bangs and blinding flashes, which come half a second apart. These grenades stun and have a seriously immobilising effect. (From experience) your head seems uncapable of functioning, you cannot see strait (if at all) and you can hear nothing but ringing. The effects last a considerable time, and leave you with a banging headache. In a situation of use, such grenades would be tossed into a room to "prepare" them for a hostage rescue clearance.
a flashbang is tossed into the room.

B A N G !!!!!!!!!!!!!!!!!

Very very very loud, trust me! The occupants of the room are stunned and find themselves unable to do anything.

Then a four man assault team takes any terrorists prisoner or immobilises any firther threat before lining up the hostages for search and check.
