Challenging all persons on or near my post is what general order of a sentry?

The correct answer is that challenging all persons on or near your post is defined in General Order 11. This order emphasizes the responsibility of a sentry to assess who approaches their post, ensuring that only authorized personnel are allowed access. This is vital for maintaining security and discipline within a military environment, as it helps prevent unauthorized entry and potential threats.

Through this order, sentries are trained to be vigilant and proactive in monitoring their surroundings. It underscores the importance of communication and command within military ranks, ensuring that protocols for identifying and challenging individuals are followed to maintain order and safety.

Each of the other general orders outlines different responsibilities for sentries, but only General Order 11 focuses specifically on the challenge aspect, making it essential for maintaining security at posts. Understanding these orders helps reinforce the fundamental principles of military discipline and procedures.
