 Military ranks used in Star Trek are all based upon actual military  ranks. Starfleet ranks are those of the US Navy: Ensign, Lieutenant  Junior Grade, Lieutenant, Lieutenant Commander, Commander, Captain,  Rear Admiral, Vice Admiral, and Admiral. Bajoran ranks are the same  as those used in the US Army, Air Force, and Marines: 2nd  lieutenant, 1st lieutenant, Captain, Major, Lieutenant Colonel (or,  as the Bajorans call it, Field Colonel), Colonel, and General.  (Kira, after her promotion, was referred to simply as Colonel, but  she was promoted two steps in rank at once.) Klingon ranks are  bekk (an enlisted rating), Ensign, Lieutenant, Commander, Captain,  Colonel, Brigadier, General, Admiral. Cardassian ranks are based on  those of the ancient Roman Empire: Gil (equivalent to a Starfleet/  US Naval Lieutenant), Glinn (Commander), Gul (Captain), and Legate  (Admiral).
