Smoke grenade

A typical design consists of a sheet steel cylinder with four emission holes on top and one on the bottom to allow smoke release when the grenade is ignited. The filler consists of 250 to 350 grams of colored smoke composition (mostly potassium chlorate, lactose, and a dye) in virtually any color. White smoke grenades typically use hexachloroethane-zinc and granular aluminum. The reaction is exothermic and though they remain intact, smoke grenade casings will often remain scalding hot for some time even after the grenade is no longer emitting smoke. Although modern smoke grenades are designed not to directly emit fire or sparks, they remain a fire hazard and are capable of igniting dry vegetation or flammable substances if used carelessly. Another type of smoke grenade is the bursting variation. These are filled with white phosphorus (WP), a pyrophoric agent that is spread quickly into a cloud by an internal bursting charge. White phosphorus burns with a brilliant yellow flame while producing copious amounts of white smoke (phosphorus pentoxide). This type of smoke grenade is favored for its ability to produce a very dense and nearly instantaneous cloud of white concealment smoke as compared to the more common solid-filler grenades which expel a slower stream of smoke over a period of roughly 1 minute. For this reason, they are favored for use in onboard grenade launching attachments on armored vehicles, which require extremely fast concealment in the event they are targeted by anti-armor weaponry and need to rapidly retreat. == Use ==

, 1967 , 2008Smoke grenades are used for several purposes. The primary use is the creation of smoke screens for concealment and the signaling of aircraft. If movement (such as flanking maneuvers or retreat) is necessary, smoke grenades can be thrown prior to movement in order to provide a wall of visual distraction that reduces the accuracy of enemy fire and temporarily deceives them as to the force's location. Smoke grenades can also be used to signal aircraft. Since locating a target from above (especially in thick forest canopy) can be nearly impossible, even with good radio contact, colored smoke grenades are often used to allow aircraft to spot them. Colored signaling smoke grenades are widely used in CASEVAC and close air support situations where quickly locating friendly ground forces is of paramount importance. Common colors are red, yellow, green and purple, and all use very brightly colored dyes to increase the likelihood of being spotted from above. == Other uses ==

firing smoke grenades Smoke grenades are functionally identical to many forms of chemical grenades (such as CS gas riot control grenades) and incendiary grenades (such as thermite grenades) which use a fuse to ignite a solid filler inside a steel canister, which then slowly propels the combustion products out through holes in the canister as the contents burn. However, the smoke grenade class is restricted to signaling and concealment under the law of war, and thus they are not considered weapons; since the vast majority are non-explosive, they remain legal for civilian use and ownership in most countries. Since the basic design of a smoke grenade (a metal canister containing a substance that burns and expels smoke when ignited) is simple, improvised smoke grenade-like devices are ubiquitous across the world. Protestors, football spectators, and airsoft enthusiasts often create their own smoke grenades using common materials. == Smoke grenades by country ==
