After crossing an intersection, what command does the Flight Leader give?

The command given by the Flight Leader after crossing an intersection is "Road guards, IN." This command signals to the road guards, who are responsible for ensuring the safety of the flight during transitions at intersections, to return to their positions within the formation or unit. It indicates that the flight has successfully crossed the intersection and is now ready to continue its march without needing additional outside assistance.

Understanding the context of why this command is appropriate emphasizes the importance of coordination and safety during movements. While the road guards are positioned to protect the flight at intersections, their responsibilities cease once the flight has cleared the area. Therefore, calling them "IN" is a way to efficiently manage the group’s formation and maintain operational flow. The other options pertain to different commands that have distinct purposes at different times, but once the intersection is crossed, having the road guards rejoin the unit is the necessary action to maintain organization.
