What is the definition of frontal fire in machine gun employment?

Frontal fire in machine gun employment is defined as occurring when the long axis of the beaten zone is at a right angle to the front of the target. This configuration allows for effective engagement of targets that are directly facing the gunner. By positioning the beaten zone perpendicular to the target, the machine gun can deliver a concentrated area of fire that maximizes the potential for hits, making it particularly effective against adversaries who are positioned in a way that presents their frontal aspect to the firing position.

Engaging targets in this manner is advantageous for controlling the battlefield, as it can create a high volume of fire over a wide area while ensuring that the firepower is aligned with the direction the enemy is most likely to advance or be found. Proper comprehension of this concept is crucial for tactical planning and execution in infantry combat scenarios.
