This unidentified officer was a field operative of the United Nations Space Command's Office of Naval Intelligence. Between 2540 and 2552, he briefed a team of Orbital Drop Shock Troopers and SPARTAN Cal-141 prior to a mission to the planet Heian, which lay deep within Covenant-controlled space. This mission resulted in the assassination of a Covenant Prophet who was responsible for supply routes in that sector of the galaxy.
- ↑ Taylor H. Miles, who participated in the mission on Heian, enlisted in 2540, meaning the mission occurred during or after 2540. During the mission, Cal wore the Mark IV Mjolnir Armor, which was replaced by the Mark V in November 2551.
