What does "AP" in ammunition types stand for?

The term "AP" in ammunition types stands for Armor Piercing. This classification indicates that the ammunition is designed to penetrate armor and thus is used primarily against vehicles or armored personnel. Armor-piercing ammunition typically includes hardened projectiles or specific design features that enhance its ability to penetrate materials that would normally stop standard bullets. This designation is important for military applications where engaging targets that might be protected by body armor or vehicle armor is necessary. Understanding the characteristics of various ammunition types, including AP, is crucial for effective tactical planning and engagement in combat scenarios.
