Chain of Command

The current commander of Galactica is Admiral Adama, and second-in-command is Colonel Tigh (Tigh has retained this position despite the revelation that he is one of the Final Five Cylons). Captain Karl Agathon has risen to third-in-command and has frequently filled in as executive officer. Beyond that the hierarchy is unclear. Major Cottle is a medical officer and outside of the chain of command, and Captain Aaron Kelly's detention ("The Son Also Rises") presumably removes him from the order of precedence.
