General Order #4 requires you to repeat all calls from posts more distant from the guardhouse than your own.

• A. To repeat all calls from posts more distant from the guardhouse than my own.
• B. To receive, obey, and pass on to the sentry who receives me: all orders...
• C. To talk to no one except in the line of duty.
• D. To give the alarm in case of fire or disorder.

Answer: (A)

The main idea is the responsibility of relaying information from the chain of posts toward the guardhouse. When you’re at a post closer to the guardhouse, you must hear and then repeat any calls from posts that are farther away, so the message travels along the line and reaches the guardhouse without being lost. This creates a reliable communication thread, ensuring alerts and instructions from distant posts are heard by the people in charge.

That’s why the statement about repeating calls from posts more distant than your own is the best fit. It directly describes that relay duty central to maintaining security and situational awareness on the post line. The other options describe different duties—obedience and passing on orders, speaking only in the line of duty, or sounding an alarm for fire or disorder—but they do not address the specific relay function required by this order.
