White phosphorus munitions - Wikipedia

White phosphorus is pyrophoric (self-ignites on contact with air), burns fiercely, and can ignite cloth, fuel, ammunition, and other combustibles. In addition to its offensive capabilities, white phosphorus is a highly efficient smoke-producing agent, reacting with air to produce an immediate blanket of phosphorus pentoxide vapor.
