The Imperial Armed Forces was the military arm of the Sith Order of Decreto responsible for controlling and maintaining the Sith Army's Sith troopers.
Under the direct control of the Commander of the Home Fleet, the Imperial Armed Forces was the second-largest of the military arms, alongside StarFleet Command. Despite the enormity of the organization, the SpecOps were independent of the Imperial Armed Forces.
The Imperial Armed Forces were also responsible for several security/police forces throughout the Sith Empire, including the Black Guard.
