What information is included on a patrol overlay?

The correct choice highlights essential components that contribute to the effective execution of a patrol operation. Including grid designators ensures that all personnel have a common understanding of specific locations on the map, which is crucial for coordination and navigation in the field. The patrol route indicates the planned path that the unit will take during the operation, allowing for strategic movement through potentially hostile areas. Checkpoints serve as crucial markers to verify progress, track time, and maintain communication during a patrol.

The inclusion of a legend on the overlay assists in interpreting various symbols, markings, and indicators used on the map, which is vital for clarity among all members of the patrol. This comprehensive approach in the overlay enhances situational awareness and minimizes the risk of confusion when conducting operations, which ultimately contributes to mission success.
