XM84 Flash

The XM84 is a flashbang grenade that affects all players. After being thrown, it "explodes" into a blinding white light, blinding all players within its radius. Depending on a player's location within the "explosion" radius, he can be blinded anywhere from 1 to 10 seconds.

This is a very effective tool to disorient enemy players. While they're blinded, players can rush in for an uncontested kill. When blinded, a player's best bet is to either run around at random or fire shots wildly. It is never wise to just stand there when blinded.
