In which situation does General Order 4 require a response?

General Order 4 specifically refers to the responsibility of a guard to relay information within the command structure, particularly when it comes to communication from distant posts. This order mandates that guards must alert their post or the commanding officer if they hear calls or signals from a distance, ensuring that messages are transmitted accurately and promptly.

By understanding this, it becomes clear that the situation described involves the necessity of communication and coordination within a military context, which is essential for maintaining operational integrity and security.

In contrast, the other options pertain to different aspects of guard duty or interactions that may not align directly with the explicit directive of General Order 4. Acknowledging a fellow guard or engaging with guests are more about social interactions rather than operational communication, and responding to fellow soldiers' requests may fall under different protocols or orders that handle interpersonal interactions in various roles rather than the specific requirement outlined in General Order 4.
