Which control measure is used for reconnaissance handover between units?

• A. Reconnaissance Handover Line
• B. Boundary
• C. Phase Line
• D. Air Control Point

Answer: (A)

Understanding how control measures support passing responsibility between units is key here. When one unit finishes reconnaissance in a sector and another unit takes over, a defined line establishes where that handover occurs, ensuring continuous, gap-free coverage. The Reconnaissance Handover Line is specifically designed for this purpose, marking the boundary where reconnaissance duties transfer from one unit to the next. This creates clear accountability and helps coordinate the transition so both units know exactly where the other’s responsibility begins and ends.

The other options serve different roles: a Boundary defines the overall area of operation for a unit, not the moment of recon handover; a Phase Line is used to coordinate movement and timing of multiple units along a planned sequence; an Air Control Point governs air operations rather than ground reconnaissance handover.
