Criminal Investigation Division

The Criminal Investigation Division is a UNSC law enforcement agency that operates under UNSC Fleet Command. The CID likely investigates crimes involving UNSC Navy or UNSC Marine Corps personnel. During an ONI training exercise, Veta Lopis claimed to be with the CID in order to have two ensigns keep Ota Gallo, a Naval commander posing as a server, from leaving.
