Which of the following is NOT an official General Order of a Sentry?

The correct answer is the Twelfth General Order, as it does not exist in the standard list of official General Orders for a sentry. The General Orders are fundamental guidelines that assist sentries in their duties, providing them with clear instructions on how to conduct themselves while on post.

The official list typically includes the first ten General Orders, which are well-documented in military training and doctrine. The Ninth, Tenth, and Eleventh General Orders are established and serve distinct purposes in maintaining security and enforceability in a military setting. For instance, the orders generally detail responsibilities such as maintaining vigilance, reporting any violations, and ensuring the safety of personnel and assets.

In summary, while the first eleven General Orders provide critical directives, the Twelfth General Order is not recognized within the established framework, making it the correct choice in this context.
