Call the room to attention and remain at such until they direct you to carry on.
When any Warrant or Commissioned officer enters a room, unless there is another officer of the same of higher grade already present. Please note that in certain rooms, such as a dining area or bathroom, rather than "Attention" the proper command would be "At ease".Generally, you call the room to attention only if a officer entering the room is of a higher rank than the people already in the room.For example, if the room is only filled with enlisted people, you would call the room to attention if an officer of any rank entered the room. Even a 2nd Lieutenant.If, say, a Lt. Colonel is already in the room, and a Major enters, you would NOT call the room to attention. However, if a full bird Colonel enters, you WOULD call the room to attention.It is common for officers to excuse a room from calling to attention if they plan to enter and leave a lot. Rooms with a lot of activity, usually have an unwritten rule that the room is only called to attention for officer who part of the staff or regular visitors. In the Command Post, for example, pilots of all ranks are common visitors. The room would usually only be called to attention for O-6 and higher. Otherwise, nothing would get done.
It doesn't have to. It shouldn't clash too badly with other things, but that can work also if you call attention to it. If you can't hide or match something, call attention to it. It makes it the focal point of the room but that can be a good thing. It's your room or house and what you like is all that is important.
