Office of Naval Intelligence Security Protocol 1A

ONI.SEC.PRTCL.1A is an Office of Naval Intelligence security protocol that restricts certain classified files and documents, or cancels searches for classified material.

First mention of the protocol was during a query by "Charlie Hotel 409871", better known as Doctor Catherine Elizabeth Halsey, head of the Spartan-II program. The protocol did not prevent her from accessing the last recorded message of Harvest's Agricultural AI Mack, but did warn that her queries would be logged.

Much later, during the Second Battle of Earth, the Superintendent logged a single HEV pod crash into the city. It attempted to identify the object, checking first the New Mombassa Police Department records, and then attempted to access the UNSC files, but its search was halted by ONI.SEC.PRTCL.1A.
