Note:
Please note that Starfleet ranks from the 2280’s on through the early 24th century are different than those shown in this chart. For those insignia please see the most current Starfleet databases. Because of confusion in using the same rank insignia during the 2260’s up until the 2280’s it was decided to change the SFMC rank insignia to something more distinctive. The current SFMC rank insignia have been in use since the 2280’s.* The uniform color shown for these ranks may be one of the three following colors; blue, gold, or red. Only one color is shown for clarity.
