When can a sentry quit their post as stated in General Order 5?

General Order 5 clearly articulates the protocol for a sentry in regards to leaving their post. The emphasis is placed on the necessity of being "properly relieved." This means that a sentry must wait until another designated individual takes over their duties before leaving. This ensures continuity in watchkeeping and maintains security, as leaving a post unattended can lead to breaches or lapses in security procedures.

This order is rooted in military discipline and accountability, reinforcing that a sentry's responsibilities are critical, and they must ensure that someone is prepared to assume those responsibilities before departing. The focus on being properly relieved helps to build a culture of responsibility and reliability within the ranks. It prevents confusion and ensures that there is always someone to fulfill the necessary duties at the post.
