One, depleted-uranium rounds sharpen kind of like a pencil as they penetrate enemy armor, giving them a better chance of busting through it. Both are dense metals, but secondary characteristics make depleted-uranium rounds particularly effective. The US military has employed both tungsten and depleted-uranium penetrators. When the round is fired, the external sabot falls off as the depleted-uranium penetrator (its dart-like tip is visible in the image) carries on to the target. US Army soldier carries a M829A4 sabot tank round to load into the loader hatch on a M1A2 SEP V2 Abrams tank. Some penetrator tank rounds, like the American M829 for the Abrams tanks, can achieve muzzle velocities greater than 5,000 feet per second, though that's not the speed at the point of impact when it strikes. "If you can do that at the right speed," he continued, "then you stand a pretty good chance of getting through the armor on the tank" to score a potential kill. "It is all about the density of the metal that's in your penetrator because you want to hit a tank with a metal that is denser than the armor of the tank," Spoehr, director of the Center for National Defense at the Heritage Foundation, said. There are, however, radioactive effects if depleted uranium enters the body.
Russia claims there's a nuclear component, which isn't true. Tungsten is a rare-earth metal, and depleted uranium is a byproduct of the uranium-enrichment process. These armor-piercing sabot rounds rely on dense metals, specifically tungsten or depleted-uranium, to punch through enemy armor. The complete round, which consists of a primer, propellant, a discardable sabot for moving it along the tank barrel, and the penetrator, are more robust and capable than shaped charges and better for pinpoint kinetic strikes at range in tank-on-tank battles. Penetrators are rods that look like an arrow and are a couple feet long and roughly as thick as a shovel handle.
