Armor piercing rounds

Armor-piercing ammunition (also known as AP Rounds) is used to penetrate hardened armored targets such as body armor, vehicle armor, concrete, tanks and other defenses, depending on the caliber of the firearms. Armor-piercing ammunition consists of a hardened steel, tungsten-carbide, or depleted uranium penetration enclosed within a softer material, such as copper or aluminum. Armor-piercing ammunition can range from rifle and pistol caliber rounds all the way up to tank rounds.
