Bureau of Operations / Legends The Bureau of Operations was one of many bureaus within Imperial Intelligence , and , along with the rest of the organization , survived the fragmentation of the Galactic Empire largely intact . It was the only bureau in the Imperial Intelligence to be called the " Bureau " . The Bureau handled the covert operations which were beyond the scope or required greater resources than those of the average system cell . The Bureau would send in a team of specialists to a sector , in effect creating an at - large system cell , or they could send a few agents to augment an already existing system cell for a single mission . Divisions . The Bureau was broken up into six distinct divisions : Surveillance . Surveillance kept watch on serious threats to the Empire . Sorting through information and unerringly selecting suspects currently involved in anti - Imperial activity , Surveillance did its job with surprising and deadly efficiency , despite their small size . At the peak of the New Order , Surveillance had less than one agent for every seventy so dedicated in COMPNOR ' s Imperial Security Bureau . Despite the huge difference in numbers between the two organizations , Surveillance was more successful than ISB in its operations , a point Surveillance took much pride in . Surveillance agents were well trained in a broad variety of skills , including combat skills , as they were expected to handle situations by themselves in the field . Surveillance agents were thoroughly briefed on everything which is known about a suspect , and were expected to make arrests , or to neutralize the suspect if an arrest appeared untenable . Usually , more than one agent was selected for an important case , and Surveillance actively solicited the help of available system cells . Infiltration . Before an agent was accepted into Infiltration proper , they were reassigned to Intelligence , where they would assist agents within the sector branches , and then later assigned to Sedition . The agents would undergo intense training and exposed to mnemiotic drugs to enhance their learning . Those who survived with their minds intact acquired a great deal of knowledge , and were then allowed into Infiltration . They would be tested to see which mission profile suited them best : a double agent , mole , or a " polwcoz " . Double agents took part in enemy actions against the Empire . Their job was to give Imperial Intelligence information to allow the Empire to deal greater damage to the Rebellion than the double agent ' s operations would do to the Empire . A mole was inserted behind enemy lines , to transfer important intelligence about enemy activities when the opportunities arose . A polwcoz was an agent who would be used once , at a critical moment when his use would be devastating to the enemy . The fate of the polwcoz agent after this critical moment is unknown . Renik . Renik was the counter - intelligence branch of the Bureau . Renik specialized in identifying and dismantling enemy intelligence operations . If a particular operation was considered to be potentially useful to the Empire , Renik would hand over all information on the enemy intelligence operation to the Infiltration branch , who would then take it from Renik and deal with it accordingly . However , if an operation was considered insignificant or too dangerous , Renik would destroy it . Saber Enterprises was a front for most of the division ' s counter - espionage operations . Diplomatic Services ( DiploServ ) . The Diplomatic Services , or DiploServ , branch of the Bureau amounted for a sizable portion of the personnel for trade and diplomatic missions found in the Empire . They also accounted for the political experts advising the Imperial planetary governors and Moffs . DiploServ personnel were well trained and expected to perform only their overt duties . Others were more clandestine agents , sent on specific anti - Rebellion missions or to establish and organize system cells within their mission area . Destabilization Branch ( Destab ) . Destabilization Branch , or Destab , was known as " the quiet branch . " No one knew much about Destab ' s operations or personnel . They were , however , known for committing full - fledged atrocities rather than legitimate intelligence operations . Officially , Destab specialized in " taking the fabric which holds a people , society or government together and unravelling it . " Agents from other branches suggested Destab ' s methods closely resembled " shredding . " They instilled pure terror into a population , and destroyed any semblance of social order . Known operatives include Secesh Trant and General Harrid Sendo . Assassination . Assassination was embraced by other agents , long considered a legitimate means of removal of key members of the opposition . Assassination ' s agents were trained to take every advantage , to use every trick and matter of subterfuge possible . Assassination was careful to select targets which mission success was probable . Their success ratio was much higher than the theoretical one .
