According to the 4th Order, when is a sentry allowed to quit their post?

A sentry is permitted to quit their post only when properly relieved. This principle is rooted in military protocol and discipline, which emphasize the importance of maintaining security and order at all times. A sentry is responsible for monitoring their designated area, and leaving the post without proper relief could compromise the safety and effectiveness of the mission.

The requirement for proper relief ensures that there is always a person in charge of observing and managing the situation, thus preventing any potential gaps in security. It reinforces the idea that every shift has a chain of responsibility, and a sentry’s duty continues until another qualified individual has taken over that responsibility.

In contrast to the correct answer, the other options fail to uphold the established protocols. Receiving orders might temporarily allow for a change in duties, but it does not automatically grant the authority to leave the post if another sentry is not present. Allowing a sentry to quit their post at any time during their shift would create a significant risk, as it could lead to unmonitored areas and lapses in vigilance. Addressing personal emergencies is important, but those situations should typically be communicated to a superior who can arrange for relief or assistance, rather than taking unilateral action.
