Specia granades
Description: You get 2 Flash Grenades. These blind and deafen the enemy for several seconds, depending on how far away they are from the initial blast. If they aren't directly facing the grenade, the flashbang doesn't do much.
If you see a Flash Grenade, try to turn around or get behind cover.
Stun Grenade

If you get stunned and you saw where the grenade came from, try to shoot there, as the enemy will most likely try to rush in.
Smoke Grenade
