What command is used to reverse the direction of a march?

The command used to reverse the direction of a march is "Rear March." This command instructs the marching unit to pivot and move in the opposite direction. When given, the individuals in the formation perform a simultaneous half turn to face the rear and then begin marching in that new direction. This movement is particularly effective in maintaining continuity during drills, as it allows for a smooth transition without disrupting the flow of the exercise.

Additionally, other commands like "Right Face," "Left Face," and "About Face" are used for changing direction, but they do not specifically instruct the unit to reverse the direction of the march. "Right Face" and "Left Face" change the direction by 90 degrees, while "About Face" turns individuals around to face the opposite direction but does not address marching in reverse. Thus, "Rear March" is the specific term for directly reversing the march direction in drill movements.
