Colonel was a high officer rank used in the militaries of various factions, most significantly in the Union of Allied Planets and, prior to and during the Unification War, the military of the Independent Planets.
One Alliance colonel served aboard a Tohoku-class cruiser during the events of Shindig. Another distinguished colonel was among the wealthy guests at the grand ball when Malcolm Reynolds first met Sir Warwick Harrow.
- In the real, modern world, Colonel is generally the highest rank possible for an officer who sees action in the field on a regular basis.
