Any military force needs a predefined hierarchy to determine the chain of command. Most military organisations differentiate between enlisted personnel and officers. The United Federation of Planets has, of the major powers in the Alpha and Beta Quadrants, the most highly structured rank structure. The rank structures of the UFP and the Romulan Star Empire are given below.
