According to General Order 5, under what circumstance can a sentry quit their post?

A sentry is responsible for the security and safety of their assigned area, and General Order 5 emphasizes the importance of maintaining that responsibility. The only circumstance under which a sentry can leave their post is when they are properly relieved by another individual who is qualified to take over their duties. This ensures that there is always a designated person monitoring the area, maintaining security and accountability.

The concept of being "properly relieved" signifies that a proper handover of responsibility must occur, allowing the new sentry to take over with full awareness of their duties. This chain of command is essential in military operations to prevent any lapse in security protocols.

Other circumstances, such as feeling overwhelmed or when the shift ends, do not align with the strict criteria set by this order. A sentry cannot leave simply due to personal feelings of stress or fatigue, and shift changes must still adhere to the procedure of being relieved. Additionally, while following instructions from a superior is generally critical in military structures, it must also align with the principle that sentries are only relieved by qualified personnel to ensure operational integrity.
