In the last season of Babylon 5, how does Lt. David Corwin (below, left;) get away with not wearing a uniform? AFAIK he's the only command-staff character that is regularly seen on-duty in shirt-and-pants instead of a full uniform.

I suspect that after President Clark was deposed he decided not to re-join EarthForce, preferring to stay on as a civilian contractor, but I don't recall anything in the regular season episodes to support this.
