Who is the only person in a platoon that is never out of step?

The platoon guide is the only person in a platoon that is always in step. This role is specifically tasked with maintaining alignment and ensuring that the entire platoon moves cohesively during drills and formations. The platoon guide serves as a reference point for the rest of the members, which is crucial during marching or any synchronized movement to maintain discipline and order.

The other roles in the platoon, such as the platoon leader, platoon sergeant, and squad leader, have different responsibilities and may need to move or react to various situations within the formation, which could lead to them being out of step at times. The platoon guide's primary function is to set the pace and keep the platoon correctly aligned, making them unique in their constant adherence to this rhythm during movements.
