No, the only weapons that were used in the Balkans were A-10 Warthog rounds. The anti-armour rounds fired by tanks are very precise; they normally hit their target. Normally they try to put two rounds through the target just to make sure it's knocked out. The A-10, on the other hand, operates in a different way. It fires hundreds of rounds at very rapid rates, and you strafe the target. So very few of the depleted uranium rounds actually hit the target. Most of them get embedded in the road or in the local environment and things like that.
Where you're talking about the environmental aspects, they arise mostly from the rounds not hitting the target but other things. You can go around and see the holes in the road. We did that, and if you dig deeply enough, you find the penetrators. They were being picked up. Teams were clearing mines and they would occasionally find the penetrators and pick them up, put them in a plastic bag, and take them back for disposal.
