How does the general order instruct sentries to manage calls from distant posts?

The correct choice highlights the critical duty of sentries in managing communications effectively while on watch. When sentries receive calls from distant posts, they are instructed to repeat them. This action ensures clarity and accuracy in the transmission of information, which is vital in high-stakes environments where miscommunication could lead to operational failures or safety hazards.

Repeating calls helps to confirm the message has been understood correctly and allows other personnel to stay informed of the situation at distant posts. It acts as a method of verification, reducing the likelihood of errors that could arise from mishearing or misunderstanding the original message.

While other options like ignoring calls or documenting them might seem like feasible actions, they do not support effective communication or situational awareness within the unit. Making a position report may be part of a sentry's responsibilities, but it is more specific and related to reporting one's own status rather than handling incoming communications from others.
