Star Trek Online Command Combadge

Set 30 years after the events of Star Trek Nemesis, players can be immersed in the prime timeline in Star Trek Online. The Romulan Empire was destroyed by the Hobus supernova, creating a split among Romulan society between the Republic and the Tal Shiar. The Federation and the Klingons are once again at war. The Borg and countless others pose a threat to the galaxy once again, and exploration has given way to conflict. 

Sometime around 2390, Starfleet uniforms were changed to the Sierra pattern. It is similar to the uniforms of the 2370's with the branch-colored cowl although more paneled in appearance. The rank pips from the collar were dropped in favor of larger, diamond pips on the right breast. The combadge was redesigned to be reminiscent of the delta insignia of the 2260's and again include the officer's branch insignia. 

This combadge is appropriate for any STO cosplay uniform.
