In General Order 9, what should a sentry do in cases not covered by instructions?

In General Order 9, a sentry is instructed to call the Corporal of the Guard in cases not covered by instructions. This order emphasizes the importance of chain of command and communication in maintaining security and order. By contacting the Corporal, the sentry ensures that any situation is handled by someone with the authority and experience to make decisions, rather than acting independently or ignoring the issue. This protocol helps to uphold the proper functioning of security measures in place, ensuring that all actions taken are appropriate and authorized. It also illustrates the principle of teamwork within the guards, as it allows for collaborative problem-solving rather than relying solely on individual judgment in potentially critical situations.
