Rooting Out Rebels and Other Traitors

ISB Rank Insignia

ISB personnel below the rank of Captain typically wear black uniforms and sometimes body armor. Distinctive white uniforms are worn by those Captain and above. The rough equivalent Imperial Naval Rank is given for the sake of comparison. In practice, all branches of the regular military give the fanatically loyal members of the ISB a wide berth

The ISB is separate from, and was established as a deliberate rival to, the Imperial Intelligence apparatus. Staffed solely by the most trusted adherents to the New Order, the ISB usually serves more of a police function than do agents of Imperial Intelligence. ISB operatives frequently identify themselves publicly, reveling in the intimidation value provided by their parent organization's sinister reputation.

The ISB concerns itself chiefly with enforcing loyalty to the Empire and rooting out Rebels wherever they may be found. Below are the officer ranks found in the organization. ISB personnel in the field frequently commandeer supporting forces drawn from the Stormtrooper Legions. Sometimes additional Imperial Army or Naval personnel are also used, depending on the needs of the mission at hand.
