What is the First General Order of a Sentry?

The First General Order of a Sentry is "To take charge of this post and all government property in view." This order emphasizes the responsibility and authority of a sentry over the designated area they are guarding, as well as the need to ensure the security of all items and equipment within their sight. It establishes a foundational duty for a sentry, highlighting that they not only monitor their surroundings but also have an obligation to protect and maintain order within their assigned zone. This characteristic is crucial in military and security operations, where vigilance and accountability are paramount.

The other options, while reflecting important aspects of a sentry's duties, do not represent the First General Order. For example, walking in a military manner pertains to the professionalism of conduct, talking only in the line of duty involves communication protocols, and reporting violations relates to the enforcement of rules and regulations. Each of these carries its significance but does not encapsulate the primary directive outlined in the First General Order. Overall, option B succinctly captures the essence of a sentry's primary responsibility.
