UNSC Office of Naval Intelligence (RelentlessRecusant)

The UNSC Office of Naval Intelligence (ONI) is premier intelligence service of the UNSC Defense Force. It integrated military, foreign, internal, and signals intelligence capabilities into a single body. It is also authorized to execute covert operations, special programs, and also to field active counterterrorism / counterintelligence field activities.
==Operational History==
During the War, ONI would become an integral part of the war effort, providing military reconnaissance, maintaining naval intelligence to account for Covenant fleets, launching small-scale special operations, and notably, hosting "special access programs"; high-risk, high-investment black projects such as SPARTAN-II, SPARTAN-III, and KING UNDER THE MOUNTAIN. ONI would become a revered and feared byword amongst UNSC regulars, and ONI would earn an almost supernatural mythology for its successes, but also for its razor efficiency without compunction for ethics nor human life. ONI officers such as Dr. Catherine Halsey, Gibson, and James Ackerson would become infamous ONI heroes, respected and feared, perpetuating the ONI legend.
Post-War, the Office of Naval Intelligence was publicly recognized by the military community for its essential role in the War effort — ONI programs such as SPARTAN-II had literally held the UNSC together against the withering storm, buying humanity precious years. Many senior ONI officers would be promoted and decorated, with Gibson being appointed the Chief of Section Three and James Ackerson the Director of Strategic Intelligence.
After the War, ONI still remained an important division of the UNSC Defense Force, responsible for countering the terrorist, insurgent, and pirate threats that emerged after the threat of the Covenant had faded away. ONI was heavily involved in manipulations of the post-War truce being brokered on SangheliosCommon Denominator. By the mid-2550s, ONI would be associated with codewords such as CUMULUS, RAINFALL, and BLUE SHIFT and would be heavily invested in covert operations with the UNSC Special Operations Command.
ONI also accounted for a significant proportion of military research, devising experimental advanced weapons systems such as INDIGO and X-1.9.
==Organization==
Its internal organization was heavily labyrinthine and complex, necessarily so to preserve plausible deniability and to compartmentalize sensitive intelligence. Divisions of the Office of Naval Intelligence included Section Three, Section One (UNSC Fleet Intelligence), the Department of Biological Warfare, the Department of Strategic Intelligence, and the Tracking Office. 
The Director of the Office of Naval Intelligence was known as the Director of Naval Intelligence, the Deputy Director of the Office of Naval Intelligence was known as the Deputy Director of Naval Intelligence. The Director of Section One was known as the Director of Fleet Intelligence, the Director of Section Three was known as the Director of Special Intelligence, and the Director of the Department of Strategic Intelligence was known as the Director of Strategic Intelligence.
