Kill every body
there is a flash bang grenade. If that's what you are refering to, it is a grenade designed to emit a loud noise, and a bright flash of light, often used by military and law enforcement. The idea being to disorientate rather than injure or kill.
The Visitor
One way I found is to use flash or stun grenades and rush them. But make sure you have gotten them good with the tactical grenade so they do not recover to fast. If they are noob-tubing then try to flash grenade them and get away as fast as you can so that they do not randomly shoot and kill you.

get his flashbang grenade and flash him then shoot him and repeat that till he dies.
