Under which order must a sentry report violations of the orders they enforce?

The correct answer is the 3rd Order to the Sentry, which mandates that a sentry must report all violations of the orders they are responsible for enforcing. This order emphasizes the importance of maintaining security and discipline by ensuring that any breach of protocol or directive is promptly communicated to a higher authority.

When a sentry observes a violation, the responsibility to report it is critical for the overall effectiveness of the security measures in place. By following this order, sentries contribute to maintaining the integrity of operations and ensuring that any potential threats are addressed promptly and efficiently. Understanding and adhering to this command is foundational in military training and helps instill a sense of duty and vigilance among personnel.
