Armor-piercing rounds are specialized ammunition designed to penetrate hard targets, such as body armor or vehicle armor. They typically feature a hardened core made from materials like steel, tungsten, or ceramic, which allows them to maintain their shape and momentum upon impact. This makes them more effective against fortified positions compared to standard bullets. These rounds are often used by military and law enforcement personnel in situations where overcoming protective gear is crucial. However, their use is regulated in many regions due to the potential for increased lethality and the specific threats they pose in combat scenarios.
