What role does the machine gun play in an attack according to its employment principles?

In the context of machine gun employment principles, the role of the machine gun as a "Base of Fire" is essential during an attack. This designation allows the machine gun to provide suppressive fire, stabilizing the battlefield dynamics and allowing maneuvering elements—such as infantry—to advance effectively.

By establishing a Base of Fire, the machine gun can deliver a continuous volume of fire aimed at enemy positions, creating a lethal zone that hinders or restricts enemy movement. This role is vital in ensuring that friendly forces can maneuver with reduced risk of being engaged by the enemy. The suppressive effect of the machine gun allows infantry to close the distance, flank, or breach enemy defenses while minimizing their exposure to enemy fire.

Additionally, using the machine gun as a Base of Fire integrates it as a key component of combined arms operations, where it supports the infantry's movement and coordination during an offensive. This strategic utilization enhances overall effectiveness in an attack, highlighting the importance of the machine gun on the battlefield.
