what about it?
Spent shell casings - the shell casing has no DP, the projectile has a core of it.

If the next Geneva Convention decides to ban DP, so be it. But for now, they are a little more effective than carpet bombing or nuclear weapons to destroy armour and fortified positions. And a lot more precise.

Depleted Uranium- the radiation level of my old watches is much higher- But I agree they may represent a long-term health risk. Not as much as enriched uranium in "devices", though.
