What is the 3rd order to the sentry?

• A. To stand at attention.
• B. To challenge suspicious persons.
• C. To report all violations of orders I am instructed to enforce.
• D. To obey all orders without question.

Answer: (C)

The third order to the sentry is about reporting violations of the orders I am instructed to enforce. This responsibility creates a clear line of accountability: if someone breaks the posted rules or if a rule is violated, the sentry must report it through the proper channels rather than taking informal action. This supports the integrity of the entire enforcement system and keeps incidents within the established chain of command.

Standing at attention is simply a postured stance, not the duty described here. Challenging suspicious persons can be part of guard duties, but it isn’t the specific obligation conveyed by this order. Obeying all orders without question is a general expectation, but it doesn’t capture the concrete duty to report violations to the appropriate authority.
