When is the flag hoisted during reveille?

The flag is hoisted during reveille at the sound of the first note of the music. This practice aligns with military customs and traditions, which dictate that the flag should be raised as a part of the ceremony that honors the national ensign and marks the beginning of the duty day. The moment the music begins signifies the formal initiation of the reveille ceremony, and it is at this moment that the flag is raised, emphasizing respect for the national colors and the significance of the occasion.

Other options, while they may sound logical, do not align with established military procedures. For example, hoisting the flag at the end of the ceremony would contradict the purpose of reveille, which is to mark the start of the day. Additionally, waiting for the sun to rise might not align with the scheduled practices that vary depending on location and season. Similarly, the flag should not be hoisted contingent upon the position of unit officers, as the ceremony is standardized and should proceed at the designated time.
