That makes me wonder, what does it mean to be a NATO officer, and is that how he would describe himself? Or would he be an officer of country X who is assigned to NATO duties at the time? Like, does he wear a NATO uniform? Or the uniform of his nationality? Are you in your countries military org chart and NATO's, or just NATO's? Or does NATO even have an independent org chart or officer hierarchy? Are there units permanently dedicated to NATO service, or is it just mapped on to national units in an ad hoc manner when needed?
