@Igualitarista hard to tell by looking at a canister in the distance, for sure. Flashbangs = stun/concussion grenades http://en.wikipedia.org/wiki/Stun_grenade …
@asteris ya, either case, it makes a noise & flash. wonder if concussion grenades differ tho in having stronger knockback effect?
@Igualitarista dunno about specific variants, but main thrown crowd control devices are gas & stun grenades. All sorts of fired projectiles
