What action should be taken as the enemy draws closer while in defense?

As the enemy draws closer while in a defensive position, increasing rates of fire is a tactical response that serves several purposes. When an enemy approaches, the intent is often to close the distance for a more advantageous engagement, potentially compromising the defensive line. By ramping up fire, defenders can create a more intense volume of suppressive fire, impacting the enemy's ability to maneuver, causing confusion, and disrupting their attack plan.

This tactic allows defenders to maintain control of the battlefield, deter enemy advances, and inflict casualties at a critical moment. The psychological effect of sustained gunfire can also lower the morale of attacking forces, potentially leading them to hesitate or retreat. Ensuring that the defensive position is well-drained of ammunition and proactively engaging the enemy helps to establish dominance in the combat scenario.

The other options—such as decreasing noise to avoid detection, preparing to retreat, or signaling for reinforcements—do not directly counter the immediate threat of the enemy closing in and may lead to a loss of defensive effectiveness. Therefore, maximizing firepower becomes essential in maintaining the integrity of a defensive stance.
