thanx very much
However, white phosphorus has a secondary effect. While much less efficient than ordinary fragmentation effects in causing casualties, white phosphorus burns quite fiercely and can set cloth, fuel, ammunition and other combustibles on fire. It also can function as an anti-personnel weapon with the compound capable of causing serious burns or death.The agent is used in bombs, artillery, and mortars, short-range missiles which burst into burning flakes of phosphorus upon impact

thanx again
