In what situation would a machine gunner be trained to perform "fire and maneuver"?

The scenario where a machine gunner performs "fire and maneuver" is essential in tactical operations, particularly during offensive and defensive engagements. This approach combines the necessity of providing suppressive fire while also repositioning to a more advantageous location.

In a situation where the gunner needs to move, maintaining effective fire on the enemy allows for safe movement of their own team or unit. This technique is vital for maintaining momentum in an assault or for ensuring cover during a withdrawal or repositioning. The ability to provide continuous suppressive fire while maneuvering supports not only the individual's safety but the safety and success of the entire team engaged in combat.

Other scenarios, such as engaging from a stationary position or conducting maintenance, do not involve the dynamic aspect of moving while shooting, which is the essence of the "fire and maneuver" tactic. Similarly, establishing a defensive perimeter typically requires a different focus, where the primary objective is to secure and hold positions rather than actively engaging targets while moving.
