(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.
