What action should the road guard take if a staff vehicle approaches the flight while crossing an intersection?

The correct answer is that the road guard should continue marching the flight across the intersection when a staff vehicle approaches. This action maintains the flow and discipline of the formation, ensuring that the flight can complete its crossing without unnecessary stoppage or disruption.

In military training and formations, it is essential to maintain the momentum and cohesion of the group. If soldiers were to halt without proper protocol, it could lead to confusion and break the formation. By allowing the flight to continue marching, the road guard respects the procedure while ensuring that the flight operates smoothly.

The role of the road guard in this scenario is to facilitate safe and efficient crossing of intersections while being vigilant about traffic, particularly when it comes to staff vehicles. This demonstrates an understanding of maintaining order and discipline, which are vital aspects of military training.
