According to the 5th General Order, when should a sentry quit their post?

The correct answer emphasizes that a sentry should quit their post when properly relieved. This principle is a fundamental aspect of military protocol, ensuring that responsibilities are handed over appropriately and that there is no lapse in security when one sentry is relieved by another. It reinforces the importance of maintaining vigilance at all times and adhering to the chain of command during duty transitions.

Ensuring that a sentry leaves their post only when properly relieved helps maintain operational effectiveness and accountability. It signifies a transfer of responsibility, preventing potential breaches in security. The emphasis on proper relief underscores the necessity of communication and coordination in preserving order within a military environment.
