Smoke Grenade/Battlefield 3

The M18 Smoke Grenade was announced as an available weapon in Battlefield 3 on the GamesCom Fact Sheet, but is not used by the player. It is only seen in non-player-controlled situations, such as the seaborne assault on Kharg Island in multiplayer. On the Co-op mission The Eleventh Hour, smoke grenades are thrown by French Police to cover the GIGN soldiers who advance into the Stock Exchange (and are subsequently gunned down).

Players do have access to other forms of smoke concealment in multiplayer, such as 40mm Smoke for the M320, and 60mm Smoke for the M224 Mortar.
