What is BHL?

• A. A territory boundary
• B. Designated phase line where responsibility transitions from stationary force to moving force and vice versa
• C. A supply point
• D. A command post location

Answer: (B)

BHL stands for the Battle Handover Line. It’s a designated phase line used to transfer responsibility and command control between forces as a maneuver unfolds. The idea is to have a clear point in space and time where the stationary force hands over control to the moving force, and later, when the movement concludes or transitions again, responsibility passes back. This keeps coordination tight during movement, clarifies who is in charge for the next segment, and helps maintain security, deconfliction, and fires coordination as units transition from stop to go and back again. It isn’t a physical boundary like a territory line, a supply point, or a command post; it’s a control line used to synchronize the shift in responsibility between forces.
