I'm not sure about Nathan. Canon mentions him being a pilot in the Navy and serving tours. Also that he went to Annapolis so he had to be an officer. The picture in dress whites likewise show it. And his campaign ads talked about him being a leader. The one image from his campaign site, it looks like he was only an Ensign in that pic according to the bars on his shoulder. He could have been in command of units at some point, but canon's not confirmed much. So probably leaves him out too.
