I've read a couple of accounts online about the use of white phosphorous in munitions during ww2 and it sounds like nasty stuff. In one account I read that an allied tanker shot a round into an abandoned bank in which the Germans had set up an anti tank gun. Apparently all that was left of them after that was their shoes. Was this stuff legal to use in the war? Once it starts burning it doesn't stop and if it happens to hit your skin it will burn right through you!
