The Abrams Tank System Program has been using [[depleted uranium]] shells and armor since the 1980s. The depleted uranium is made of a particular hardened "man-made" element, harder than lead, steel, or iron. So-called "amour piercing shells" of depleted uranium can slice through or melt lead, steel, or iron, while artillery shells made of those metals cannot penetrate the armour. Use of depleted uranium shells causes longterm [[environmental]] damage, and the lasting danger to humans of exposure to [[cancer]] causing [[radiation]]. | The Abrams Tank System Program has been using [[depleted uranium]] shells and armor since the 1980s.
