What is the primary responsibility outlined in General Order 11?

General Order 11 specifically emphasizes the responsibility of challenging all persons near a post. This order is a key principle in the military and security fields, focusing on the necessity of vigilance and identification verification. The act of challenging individuals serves to maintain security and safety in a given area, ensuring that only authorized personnel can access specific locations.

This responsibility is crucial for preventing unauthorized access and upholding the integrity of the secured environment. While the other options address various aspects of security and teamwork, they do not capture the core essence of the duties specified in General Order 11. The emphasis on challenging individuals is fundamental to the role of personnel tasked with guarding, as it actively engages them in their duty to protect and maintain order.
