Sith Fleet Officers, also referred to as Sith officers, or Sith Eternal officers, were primarily human military officers who possessed command roles and duties within the Sith Eternal's naval forces and ground troops.
The debut of the Sith Eternal officers occurred in the 2019 motion picture Star Wars: Episode IX The Rise of Skywalker, which concluded the Star Wars sequel trilogy. Their formal designation was provided in Star Wars: The Rise of Skywalker: The Visual Dictionary, penned by Pablo Hidalgo, which became available concurrently with the film's release.
