Name one characteristic of the .50 caliber machine gun.

The .50 caliber machine gun is renowned for its capability to fire armor-piercing rounds, which is one of its defining characteristics. This feature makes it particularly effective against a variety of targets, including lightly armored vehicles, aircraft, and personnel in protective gear. The armor-piercing ammunition used with the .50 caliber gun is designed with a hardened core, allowing it to penetrate armor and provide increased lethality on the battlefield. This capacity for delivering powerful, penetrating fire distinguishes it from many smaller caliber machine guns and enhances its role as a heavy weapon in military operations.
