What command does the platoon commander issue to close ranks?

The command to close ranks is "Close ranks, march." This command is a direct and clear instruction for the platoon to adjust its formation by moving closer together. It is fundamental in maintaining proper spacing and organization within the unit, particularly during drills, parades, or when preparing for further movements. By issuing this command, the platoon commander facilitates a tighter formation, which can enhance the visibility and cohesion of the unit as a whole.

In the context of drill practice, other commands serve different purposes. Commands like "At ease" allow for a more relaxed posture among cadets without changing their formation. "Fall in" is issued to form or assemble the unit, while "Stand by" typically indicates a preparatory stance for an upcoming command. Thus, "Close ranks, march" specifically addresses the need for the platoon to adjust its position in a compact formation.
