UNSC Code Three-Nine-Two

Code Three-Nine-Two is a UNSC code term brandished by Special Warfare teams to ignore hails from other forces due to a higher-priority mission. Dr. Halsey used this code when Admiral Whitcomb hailed her over Eridanus Secundus when she was fleeing in the Beatrice. The Admiral took it personally, interpreting it as Dr. Halsey had "just told me to go to hell."
