uming the two people are the same rank, is adultery a crime under the Uniform Code of Military Justice?

If two people in the military engage in adultery, is that considered a crime? I know it is frowned upon because cheating on someone's wife tends to break down morale and cohesion in a unit, which is true in any workplace. But I thought I've read about people getting disciplined for it, either criminally or administratively. (If one's an officer, that's different and not the subject of my question.)
