What should the fourth rank do during open ranks?

During the open ranks maneuver, the fourth rank is required to move two steps backward. This action creates proper spacing and alignment among the ranks, allowing those in front to have space for effective execution of commands and movements. The fourth rank's step backward ensures that the formation remains organized and that all ranks can clearly see, hear, and respond to commands from their commanding officer.

The requirement for the fourth rank to move backward helps maintain a structured appearance in formation, enabling better visibility and coordination within the unit. Proper spacing is crucial for efficiency and maintaining discipline in drills and exercises.
