What does the term 'suppressive fire' signify in military terms?

The term 'suppressive fire' in military terminology refers specifically to fire that is directed at enemy forces to prevent them from moving or effectively targeting friendly units. This form of fire is crucial during combat as it reduces the enemy's ability to shoot accurately, maneuver, or conduct operations due to the perceived threat of incoming fire.

By maintaining pressure on enemy positions, suppressive fire allows friendly forces to maneuver, reposition, or engage the enemy under more favorable conditions. This tactical action supports the overall mission by creating a temporary advantage for friendly forces while limiting the effectiveness of the enemy.

In contrast, the other options describe different types of fire. While destroying equipment or securing landing zones is important, they do not encapsulate the primary intent of suppressive fire, which is to hinder enemy movement and actions. Similarly, illuminating areas for night operations serves a different purpose focused on visibility rather than suppression.
