Nitpick: the RCC (at least, the one I work for) has an FTS CO, FTS CSO, and a SELRES Deputy. There seem to be a lot of aviators that cycle through my front office, as well as a bunch of aviators filling NOSC CO billets.There is still the RCC (SELRES guy who is the boss) and the OIC (FTS guy who actually does the day to day stuff, usually has a YN working for him), although we stopped calling it the OIC since that term has crappy job recognition on promotion boards.
