According to the 6th General Order, what is a sentry required to do?

The role of a sentry in a military context, particularly under the 6th General Order, emphasizes their responsibility in communication within the chain of command. The correct answer focuses on the duty of a sentry to "receive and pass on orders." This aspect is critical as it reflects the importance of relaying information accurately and efficiently to ensure operational readiness and adherence to protocols.

Sentries play a vital role in maintaining security and order. By being tasked with passing on orders, they act as a critical link between different levels of the command structure, ensuring that instructions and directives are not only received but also communicated effectively to others, thereby maintaining a smooth flow of information.

The other options speak to various aspects that may be related to a sentry’s duties but do not capture the specific requirement set forth in the 6th General Order, which is primarily concerned with the exchange of orders as a fundamental responsibility of a sentry.
