What action do military personnel take when the flag is lowered?

When the flag is lowered, military personnel are required to demonstrate respect and honor for the flag and what it represents. This is accomplished by saluting and standing at attention. The salute is a formal gesture of respect to the flag, symbolizing the military's commitment to its country, while standing at attention conveys readiness and solemnity during this significant moment.

The act of saluting while standing at attention is an established protocol within the military, emphasizing the importance of the flag as a national symbol and the sacrifices made by those who serve. This practice fosters a strong sense of discipline and unity among service members, reinforcing their duty to uphold the values and traditions of the military.

The other choices do not align with military customs regarding the flag etiquette. Remaining seated fails to show the necessary respect during such a significant moment. Standing at ease indicates a more relaxed posture that does not convey the same level of respect. Clapping is not an appropriate response in this context since it is not traditional or respectful in military protocol.
