The second general order of a sentry is to remain alert and observe everything. This guideline emphasizes the importance of vigilance in a sentry's role, ensuring they are fully aware of their surroundings at all times. This heightened awareness is crucial for the security and safety of the area they are assigned to protect, as it allows them to detect any potential threats or unauthorized individuals.

Remaining alert encompasses not only observing for immediate dangers but also monitoring changes in the environment or activities happening within their vicinity. Such attentiveness can lead to timely reporting and responses to any irregularities, which is vital in maintaining an effective security posture.

This principle of vigilance aligns with the overall responsibilities of a sentry, who must always be prepared to respond appropriately to any situation that arises, thus enhancing the overall mission effectiveness.
