In the 5th General Order of a Sentry, when can a sentry leave their post?

In the 5th General Order of a Sentry, the emphasis is on the importance of duty and the protocol surrounding the responsibilities of a sentry. The correct answer highlights that a sentry can only leave their post when they have been "properly relieved." This means they must receive a formal handover from another designated individual who is authorized to assume their duties, ensuring that there is no lapse in security or oversight.

The phrase "properly relieved" indicates that the previous sentry must confirm that their responsibilities have been officially transferred to another sentry. This requirement helps maintain accountability and operational security, which are critical in a military environment. It ensures that the post remains monitored and that there is continuity in the execution of orders.

Other choices do not align with this established protocol. For example, leaving post because a friend has arrived does not meet the necessary formal process of relief. Reporting to the Officer of the Deck (OOD) is important, but it is not directly related to when a sentry can leave their post. Lastly, feeling like it is certainly not a justifiable reason, as it undermines the discipline and structure necessary for effective military operations.
