Which order requires the sentry to repeat calls from a distant post?

The correct response to the question about which order requires the sentry to repeat calls from a distant post is the fourth order. This order is part of the general guidelines for sentries, which emphasize the importance of communication and situational awareness in security roles.

The fourth order specifically instructs sentries to relay any calls they hear from other posts. This is essential because it helps maintain an effective communication network, ensuring that all personnel are aware of potential threats or important events happening in their vicinity. By repeating calls from distant posts, sentries can keep their own post informed and help coordinate responses among team members, which is crucial in maintaining security and safety.

In contrast, the other orders focus on different aspects of sentry duty, such as maintaining vigilance, reporting any suspicious activity, or allowing personnel to pass. While all these orders are vital for a sentry's responsibilities, the specific focus on repeating distant calls is uniquely covered by the fourth order. This ensures a cohesive and well-informed security posture.
