Present Senior Staff

CIC

• Admiral William Adama - Commanding Officer
• Colonel Saul Tigh - Executive Officer (on leave)

Chain of Command

Presently, the first in command aboard Galactica is Admiral Adama, and the second in command is Captain Agathon. Beyond that the hierarchy is unclear. Major Cottle is a staff officer and outside of the chain of command. Given Captain Kelly's detention in "The Son Also Rises" he is presumably no longer a candidate.
