AP (armor-piercing) ammunition

Armor-piercing (AP) ammunition is specially designed bullets that can penetrate armored targets, like vehicles or military equipment. They typically feature a dense, hard core—often made of materials like hardened steel or tungsten—that maintains shape and momentum upon impact, allowing the bullet to breach tough armor. AP rounds are engineered to maximize penetration with minimal deformation, making them effective against armored threats. They are used primarily in military applications where penetrating defenses is necessary, but due to their potential for destructive use, their possession and use are often regulated by law.
