What is the requirement under the 7th Order to the Sentry?

The requirement under the 7th Order to the Sentry is to "talk to no one except in the line of duty." This emphasizes the importance of maintaining security and discipline while on duty. It ensures that the sentry remains focused on their responsibilities without getting distracted by outside conversations or interactions. This order is critical in maintaining the integrity of military operations, ensuring that sensitive information remains confidential and that the sentry can respond promptly if any security issues arise.

While other choices reflect important aspects of military conduct, they do not represent the specific requirement of the 7th Order to the Sentry. Saluting, passing on orders, and giving an alarm are necessary actions but pertain to different orders or responsibilities within the overall framework of military duty. The 7th Order specifically addresses interactions with others, underscoring the sentry's need for vigilance and professionalism.
