What enables maneuver forces to close in on an enemy target?

Effective suppression of the threat is crucial in enabling maneuver forces to close in on an enemy target because it mitigates the enemy's ability to engage and respond effectively. When the threat is suppressed, either through direct fire, obstructions, or other means, it limits the enemy’s observational capabilities, reduces their firepower, and decreases their overall combat effectiveness. This allows maneuvering units to advance with greater safety and speed, as they are less likely to come under effective hostile fire.

In contrast, while heavy artillery support, distracting tactics, and rapid unit movements can contribute to a tactical advantage, they do not directly address the need to minimize the enemy's capacity to retaliate. Suppression of enemy threats ensures that maneuver forces can close in without facing immediate danger, allowing for more successful engagements.
