What must you do according to the 4th General Order of a Sentry?

The statement that aligns with the 4th General Order of a Sentry is that a sentry must repeat all calls from any post more distant from the guardhouse. This order is important because it ensures clear communication and awareness among the guards and the personnel within the area. By repeating calls from distant posts, the sentry helps to maintain a constant and effective line of communication, which is crucial for security operations, coordination, and situational awareness. It demonstrates the responsibility of the sentry to facilitate a cohesive and organized response to any developments that may occur within their vicinity.

Other options, such as taking charge of the post, reporting suspicious activity, or obeying orders from an officer, pertain to different general orders and responsibilities assigned to sentries, reflecting the broader duties one must adhere to, but they do not specifically define the 4th General Order.
