Who must inspect the interior guard during the night?

The Officer of the Day is tasked with inspecting the interior guard during nighttime to ensure that all personnel are performing their duties correctly and maintaining the security of the area. This responsibility falls on the Officer of the Day because they are in charge of the overall operations during their shift, including overseeing the guard's effectiveness and addressing any issues that may arise.

The inspection is a critical task, as it not only reinforces discipline but also boosts the morale of the guard staff by showing that their efforts are being monitored and valued. It also ensures that any deviations from standard operating procedures are quickly identified and rectified, thereby maintaining a high level of security and readiness.

While other ranks such as the Corporal of the Guard, the Sergeant of the Guard, and the Commander of the Guard have complementing roles within the guard structure, the final authority during such inspections rests with the Officer of the Day. This hierarchical system emphasizes accountability and clear chains of command necessary for effective military operations.
