H-20: Reduce

Previous: H-17: Secure

H-20. Reduction is the creation of lanes through or over an obstacle to allow an attacking force to pass. The number and width of lanes created varies with the enemy situation, the assault force’s size, composition, and scheme of maneuver. The lanes must allow the assault force to rapidly pass through the obstacle. The breach force will reduce proof (if required), mark, and report lane locations and lane-marking method to higher command headquarters. Follow-on units will reduce or clear the obstacle when required. Reduction cannot be accomplished until suppression and obscuration are in place, the obstacle has been identified, and point of breach is secure.
