What is a key responsibility of a machine gunner during a fire mission?

The key responsibility of a machine gunner during a fire mission is to maintain the weapon and ensure its operational readiness. This role is crucial because the effectiveness of the machine gunner is heavily dependent on their ability to keep the weapon in optimal working condition throughout the mission. This includes regular cleaning, proper lubrication, and immediate troubleshooting of any malfunctions. A well-maintained weapon ensures that it can deliver sustained and accurate fire, which is essential for supporting infantry and achieving mission objectives. The machine gunner must also be familiar with the weapon's operation and capabilities to effectively engage targets, react to changing battlefield conditions, and provide reliable fire support.

Coordination of logistics for ammunition supply, providing medical support, and managing engagement strategies may involve other personnel on the battlefield but are not primarily the responsibilities of the machine gunner during a fire mission.
