Q: Can a married soldier be in a singe soldier room

A: Maybe. Maybe not. I can't tell very much from the pitiably small amount of information you have provided. It sounds to me like the 'married soldier,' (I'm guessing that's you) is in trouble for being in the barracks room of the 'single soldier.' One of the things about being in the military is that there are a whole lot of things that can be illegal that aren't illegal for the rest of humanity. The Uniform Code of Military Justice is a list of laws that soldiers are expected to abide by. There is nothing in the UCMJ about married soldiers being banned from the barracks rooms of single soldiers. However, the UCMJ has a LOT to say about obeying orders. If an officer or NCO ordered you to stay out of the rooms of singles soldiers, then you are bound by that order. If there is a standing order on your installation prohibiting married soldiers from entering single soldier's quarters, then you better stay out! Plus, it's just good common sense for a married person to stay out of the bedroom of a single person. It just looks bad, and there are too many temptations. Don't give me any of that, 'We're just good friends' nonsense. If my wife learned that I had been 'visiting' in the bedroom of a 'really good friend' who just happened to be a girl...Like Lucy Ricardo, I'd have a "whole lot of 'splainin' to do." If you have just a general legal question about this, you have a legal assistance office on your installation. You can make an appointment to get some clearer advice. If you are in trouble and facing nonjudicial punishment or something worse, you need to seek out the Trial Defense Service on your installation. They can provide you with advice or representation.
