The Office of Military Intelligence or OMI is the Sioux Nation's intelligence agency. While it typically focuses on intelligence efforts on the UCAS and CAS, it is known to have agents in other NAN states. It also watches megacorps involved in Sioux affairs. The director is known only by her code name, Sinopa.
In 2054, the OMI went through a series of embarrassing disclosures that revealed the organization to be a failure on many accounts. The organization was purged, and Sinopa took the helm. Sinopa changed the organization to also handle counter-intelligence and internal security, effectively putting surveillance on the entire Sioux Nation population for national security.
