What should you do if an officer enters the room?

When an officer enters a room, the correct action is to stand at attention as a mark of respect. This action reflects military courtesy and discipline, showing recognition of the officer’s rank and position. Standing at attention conveys readiness and respect for authority, which is fundamental in military settings where hierarchy is important.

Remaining seated or continuing to eat would not demonstrate the appropriate respect for the officer entering the room. Saluting is generally reserved for specific situations, such as when engaging with an officer outdoors or in certain ceremonial contexts; it is not the immediate action taken upon their entry into a room. Hence, standing at attention is the most appropriate response in this situation.
