in some games, you can see thru smoke screens using thermal goggles or other special sci fi optics. but, your own team suddenly having that equipment, and only turning it on when your smoke grenade is active, just because you brought smoke grenades, is a little funny.
maybe the smoke grenade is meant to work in conjunction with the vet power that outlines enemies? but a grenades usefulness shouldnt be too deeply tied with another ability, it should remain useful on its own
