The Office of Naval Intelligence often operates independently of other UNSC
branches. At times it contravenes the law and UNSC protocol to complete top-secret missions. It appears to have an unusually large amount of military equipment for an intelligence service, and has a strong fleet presence. The Office of Naval Intelligence possesses a destroyer-sized prowler-class starship, UNSC Point of No Return
, which is used as a command vessel and a secure conference location. ONI also maintains the UNSC's Prowler
fleet, a major source of Covenant
deployment intelligence, under the auspices of the UNSC Prowler Corps
. ONI also manages field intelligence with units such as ONI Recon 111
liaising with mainstream UNSC military units.
Intra-ONI dynamics are often strained with intense competition amongst its own personnel. Agents operate under heavy scrutiny with mistakes often leading to demotion or death.
