How does the platoon commander finalize the inspection of each platoon?

The correct choice of commanding "Parade rest" serves a specific purpose in the context of finalizing the inspection of each platoon. When the platoon commander gives the command to "Parade rest," it allows the members of the platoon to transition from a position of attention to a more relaxed stance while still maintaining an element of discipline and readiness. This command indicates that the inspection is concluded, providing a clear signal for the cadets to ease their posture without losing their military bearing.

"Parade rest" is commonly used in formal military contexts to show that the formation will remain in an orderly state, even as the members are permitted to relax slightly. This command also signifies respect for the authority of the commander, as the cadets maintain attention to their leader while being allowed to stand more comfortably. It reinforces the idea of discipline within the ranks while effectively communicating the end of the inspection procedure.
