Which General Order requires you to be especially watchful at night and during the time for challenging, to challenge all persons on or near your post and to allow no one to pass without proper authority?

• A. General Order #9
• B. General Order #10
• C. General Order #11
• D. General Order #12

Answer: (C)

The key idea here is the duty of a sentry to control access and stay vigilant, especially when visibility is reduced. The instruction that says you must be especially watchful at night and during challenging times, and that you should challenge all persons on or near your post and not let anyone pass without proper authority, directly embodies this protective guard role. It establishes the responsibility to actively identify and question anyone trying to approach, ensuring only authorized individuals proceed.

This is why that statement is the best match: it explicitly ties vigilance to entry control and authority-based passage, which is the essence of a sentry’s duty in this context. The other statements describe different duties—calling the officer of the deck for cases not covered, saluting officers and colors, or refer to duties not aligned with the night-time challenge and access control—so they don’t fit the described scenario as precisely.
