When is it permissible to leave a post according to the general orders?

Leaving a post is permissible when an individual has been properly relieved. This means that a designated individual, typically a superior, has officially taken over the responsibilities of that post. Proper relief is crucial in maintaining security and ensuring that no gaps exist in responsibility. It is a matter of following protocol; each person in a security role must be accountable for their area until they are officially transferred to another. This maintains the integrity of the post and ensures that all duties are fulfilled without lapse.

In contrast, other scenarios—such as leaving when a shift ends or feeling tired—don't adhere to the strict guidelines that dictate when a sentry or guard can vacate their post. Although it might seem reasonable to leave once their shift is over, the critical point is that official relief must take place. Meanwhile, leaving due to personal feelings of fatigue or because no responsibilities seem present undermines the reliability of the position and can lead to lapses in security. Protocol emphasizes the importance of having a designated person responsible for the post at all times, highlighting why proper relief is essential.
