Besides recoil, what other aspect is crucial for successful machine gun operation?

Coordination with infantry units is a vital aspect of successful machine gun operation because it ensures that the machine gun effectively supports the overall tactical goals of the unit. Machine guns are typically employed to provide suppressive fire, cover, and support during assaults, and they must work in harmony with the movements and actions of infantry soldiers. This coordination facilitates effective fire control, situational awareness, and the ability to saturate enemy positions while minimizing the risk to friendly forces.

Proper communication and planning between machine gunners and infantry units are crucial to achieving desired outcomes in combat situations. For example, by coordinating when and where machine gun fire is applied, infantry soldiers can maneuver more freely and effectively, utilizing the firepower of the machine gun as a force multiplier. This cohesiveness directly influences the success of operations and the safety of all personnel involved.
