Makes America’s Tanks UnstoppableA tank is a fast-moving, well-protected, heavily armed behemoth designed to dominate the land battlefield. As the primary offensive weapon in any army, nations compete to field the best tanks in both peace and war.
In the 1980s, the U.S. Army took the drastic step of arming its tank, the M1 Abrams, with the ultimate upgrade: a tank-killing round made of uranium, the heaviest naturally occurring element on Earth. The result is an unmatched tank killer capable of destroying any fielded tank.
