What commands are given to dismiss a platoon armed with rifles?

The commands for dismissing a platoon armed with rifles are structured to ensure the troops transition from a state of attention to being dismissed in an orderly fashion. The sequence of "Inspection arms, Port arms, Dismissed" allows for a proper display of the rifles before the platoon is dismissed.

"Inspection arms" is the command that directs Marines to bring their rifles to a position where they can be inspected. This command emphasizes the importance of handling their weapons carefully and respectfully, even in a casual context. Following this, "Port arms" instructs the Marines to bring their rifles to a ready position that is secure and more relaxed than the position of attention. Finally, the command "Dismissed" signals the Marines that they may leave the formation, transitioning smoothly from a military posture to a more informal state.

This sequence reflects fundamental military protocol, ensuring that weapons are properly handled while allowing for an organized release of duties. Other options may include commands that are not standard for dismissing a formation with arms, which is why they do not fit the scenario as precisely.
