What commands should be given to dismiss a platoon armed with rifles?

The correct sequence of commands to dismiss a platoon armed with rifles is Inspection arms, Port Arms, Dismissed. This sequence ensures that the safety and order of the platoon are maintained as they transition from a position of attention to being dismissed.

Starting with "Inspection arms," the command ensures that all weapons are inspected for safety and readiness. This is particularly important for maintaining discipline and ensuring that all Marines are accountable for their weapons before they are dismissed. Following this command with "Port Arms" positions the rifle in a safe and controlled manner while still keeping it under control. This stance allows the personnel to prepare for dismissal properly without having their weapons in an unsafe position.

The final command, "Dismissed," ordains that the troops can move out and separate from formation. This particular sequence is important in ceremonies or formal settings to uphold military traditions and ensure proper handling of weapons throughout the process.

Other options do not follow the correct protocols for dismissing a platoon with rifles, either by using incorrect positions for the weapons or not adhering to the standard commands necessary for proper military procedure.
