What is one of the general orders of a sentry?

One of the general orders of a sentry is to take charge of the area and government property. This directive emphasizes the responsibility of the sentry to maintain security and protect property within their designated area. It entails being vigilant and observant, ensuring that any unauthorized personnel or activities are addressed promptly to prevent potential breaches of security.

The other options do not align with the primary purpose of a sentry. Enforcing civilian laws or patrolling the local community focuses more on law enforcement rather than the specific duties of a military sentry. Monitoring communications may be part of a different role, such as that of a communicator or signal officer, but is not a general order for sentries. Thus, the correct answer highlights the fundamental duty of a sentry to safeguard the assigned area and the property under their watch.
