ONI Security

ONI Security is the personal security force of the Office of Naval Intelligence.

Background
ONI Security is comprised mainly of recruited Army and Marine candidates. Their alignment is under the UNSC Navy, and jurisdictionally under the Naval Special Warfare group, which allows them some autonomy under ONI's management. The detachment on Ivanoff Station was used primarily for science team protection on Gamma Halo, in the rare case of emergency or attack. When the Ur-Didact attacked the station, ONI security engaged the Covenant remnant forces attacking the station. The entire detachment was killed either by the Covenant remnant or composed by the Ur-Didact.

Equipment
ONI security is generally equipped with a black Marine BDU, with some additions. The pauldrons are reinforced for heavy combat. The armor is made with a specialized composite engineered by ONI. Some are also equipped with rebreathers.
