What happens to breached lanes during the breach process?

During the breach process, breached lanes are typically handed off to follow-on forces. This handoff is crucial for maintaining the momentum of the offensive operation after the initial assault has created pathways through enemy defenses. As the breaching forces complete their objective of creating access through obstacles—be it fortifications, minefields, or other barriers—they focus on securing and exploiting those lanes for follow-on units.

By transferring responsibility to follow-on forces, the breach can be protected, and additional troops can move through, supporting the concept of combined arms operations. This practice allows the breaching units to redeploy to continue their mission or address other operational needs, while follow-on forces take advantage of the newly established lanes to advance deeper into enemy territory. The successful transition ensures that the element of surprise and tactical advantage gained during the breach is not wasted.

Other options suggest actions such as abandoning, fortifying, or permanently clearing lanes, which do not reflect the primary tactical goal during a breach. Instead, the focus is on enabling sustained operations and exploitation of the breach by subsequent forces.
