What is the 7th general order of a sentry?

The 7th general order of a sentry is "To talk to no one except in the line of duty." This order is crucial as it emphasizes the need for discipline and focus in a sentry's role. It ensures that a sentry remains vigilant, maintains professional communication, and does not get distracted or misled by casual interactions. This order is fundamental in securing the area and ensuring that the sentry can adequately perform their duties without outside interference or diversion.

While the other options refer to various responsibilities that could be associated with sentries or security roles, they do not specifically represent the established general orders as outlined in military doctrine. For instance, guarding entrances and inspecting equipment relate more to specific tasks rather than protocols about communication, while reporting violations pertains to the duty of vigilance but is not stated as the 7th general order. Understanding these distinctions is essential for recognizing the importance of communication discipline in the context of sentry duties.
