In a four-squad platoon, how many steps does the fourth squad take on the command "Open Ranks March"?

In a four-squad platoon, the command "Open Ranks, March" is executed to expand the formation, allowing for better spacing between the squads. The fourth squad is situated at the rear of the formation, and its action during this command involves creating space so that the other squads can also align properly.

When the command is given, the first squad moves forward, the second squad remains in place, the third squad steps back, and the fourth squad takes steps backwards to ensure that all the squads are appropriately spaced apart. Specifically, the fourth squad takes two fifteen-inch steps backwards. This pattern allows the formation to expand evenly, enabling a proper alignment of all personnel. Hence, the action taken by the fourth squad accurately follows the established drill regulations for "Open Ranks, March".
