Chain of Command

Presently, the first in command aboard Galactica is Admiral Adama, and the second in command is Colonel Tigh. Beyond that the hierarchy is unclear. Major Lee Adama is the next highest ranking officer (Major Cottle is a staff officer and outside of the chain of command). However, in past episodes both Captain Kelly and Captain Agathon have have served as seconds-in-command. While Lee Adama is on parole in "Scattered", and might have been passed over because of that, it is also possible that the CAG is not in line for the command of a battlestar. Given Captain Kelly's detention in "The Son Also Rises" he is presumably no longer a candidate.
