Which graphic control measure is included in the area reconnaissance set?

• A. Phase Lines
• B. LD
• C. Rally Points
• D. Check Points

Answer: (A)

Graphic control measures in area reconnaissance are used to shape how scouts cover the map, assign sectors, and keep movement coordinated. Phase lines are the map-specified boundaries that divide the area into manageable zones or phases of operation, providing clear sectors for reconnaissance and a time-ordered progression to advance from one phase to the next. This makes it easier to synchronize actions, coordinate with fires and adjacent units, and prevent gaps or overlaps as the area is swept.

Rally points and check points are more about regrouping and verifying progress along a route, while the line of departure marks where an attack or movement begins—functions that don’t establish the broad, area-wide sequencing that phase lines provide for area reconnaissance.
