In a four-squad platoon, how many steps does the fourth squad take on the command open ranks march?

In the context of a four-squad platoon executing the command "open ranks, march," the fourth squad is instructed to move two fifteen-inch steps backwards. This movement is part of the drill and ceremony procedures that allow for proper spacing between squads.

When the command is given, the first squad will typically move forward, while the subsequent squads adjust their positions in a way that maintains formation and allows for appropriate distances between them. The fourth squad, being the last in line and positioned at the rear, has the responsibility to move backward to create space between itself and the squad in front. Moving two fifteen-inch steps backwards ensures that there is adequate separation for maneuverability, visibility, and alignment with the other squads while still maintaining the overall formation integrity.

This procedure is important in ensuring that formations are properly spaced and visually appealing during military movements, which enhances the overall professionalism and discipline of the unit.
