Though I think I understand what you are saying which is simply "write what you know", I believe that your conclusion is necessarily a non sequitor. Nobody has experience in orbital ops, not even the top military brass (at least so far as we've been told) so in that sense the OP is on level footing with other sci-fi writers. As for the "feel" of military service - that can be overcome with research and asking questions. So far, so good.
