ONI Section Zero

ONI Section Zero or Section 0, is a subdivision of the Office of Naval Intelligence.

History
Starting in at least 2550, Section Zero began to monitor Subject D and Subject S, over their conversations about Atriox. This monitoring continued until 2558 when Subject D stopped communications with Subject S.

After being recovered during Operation: WHITE GLOVE by ONI Section Three, Dr. Halsey's personal journal ended up in the hands of Section Zero.

After the Human-Covenant war, Section Zero developed their own MJOLNIR visor dubbed "Secrets."

Duties
"...Section Zero, which thinks it spies on everyone else, tells lies to Section Two, and thinks it tells lies to Sections One and Three..."

- Black-Box speaking to Kilo-Five.

The true nature and activities of Section Zero are highly classified and unknown outside the ONI command hierarchy. Zero is, essentially, an internal investigations division that polices other ONI activities, and based on the records of the AI Melissa, it is charged with rooting out and eliminating illegal programs. Part of how Section Zero achieves its goals is through monitoring personnel communications.

This section has gained notoriety as the section that keeps and maintains sealed SPARTAN-I Program file archives, including Avery Johnson's. As Internal Affairs it enforces the rules and ensures standards are met. It is authorized to use lethal force in the course of its operations.
