if I remember right. actually, very little 'penetrating' on DU rounds. They ignite from the pressure and burn through (like a cutting torch) rather than push or penetrate through. Between 30 and 70 percent of the DU, depending on thickness and toughness of what is hit, aerosolizes. 2000 tons used in Iraq. that would make about 1000 tons of aerosol. food, water, air, plants, animals. nothing escapes. Aerosols typically travel around 50 to 100 miles before settling, if ever. millions of tons stored in America. it's a waste product of reactors. Agree, keep the damn things In tanks. Not shot out of them. The war was based on lies. The war is Unconstitutional (war seems to be reserved for a direct attack against this nation, still checking info on that). Get the tanks back over here and keep the damn DU in them
