For which purpose is the M2 .50 caliber machine gun primarily designed?

The M2 .50 caliber machine gun is primarily designed for armor-piercing attacks, making it highly effective against lightly armored vehicles and enemy fortifications. Its .50 caliber round possesses significant stopping power and greater muzzle velocity compared to smaller caliber rounds, allowing it to penetrate armor effectively. This capability is crucial for engaging targets that may be resistant to smaller caliber munitions, which is why the M2 is often utilized in anti-armor roles on the battlefield.

While it can also be employed in aerial support, anti-infantry operations, and general support roles, its primary design focus is on delivering high-velocity, armor-piercing projectiles. This specialization makes the M2 an essential asset in military engagements where defeating armored threats is a priority.
