Smoke Grenade



Smoke grenades are used in the Call of Duty series as signaling devices, target or landing zone marking devices, and concealment devices. The body is a sheet-steel cylinder with emission holes in the top and bottom. These allow the smoke to be released when the grenade is ignited. The M18 colored smoke grenade is used in Call of Duty: United Offensive and the M83 white smoke grenade is used in Call of Duty 4: Modern Warfare. The M83's filler is 11 ounces of terephthalic acid. While not intended as a primary effect, the M83 smoke grenade can generate enough heat to scald or burn unprotected skin.

Multiplayer Tactics
Like in the campaign, smoke grenades can be used to obscure an area and allow players to move across an open area without being effectively targeted. It is advised to allow the smoke to fully spread before moving through the open area. Smoke grenades can be thrown in front an enemy's position, effectively blinding them. This gives players the chance to advance or flank the enemy's position. Smoke can also be used on Objective Modes such as Headquarters, Search & Destroy, and Domination to rally teammates to a location or for concealment in an objective area. However, this is generally not a very effective means of concealment since players must stay within the area covered by the smoke, and are likely to be killed by enemy fragmentation grenades. Smoke grenades can also be used to create distractions and feints, such as in Search and Destroy.
