“Sir, O'Brien's down.”

O'Brien was a member of the UNSC Marine Corps who participated in the Human-Covenant war.[1] He was an Orbital Drop Shock Trooper of the 105th ODST Division contingent aboard the UNSC In Amber Clad.


Battle of MombasaEdit

During the Battle of Earth, his squad was dispatched from the In Amber Clad to relieve Marine ground forces fighting the Covenant Army in New Mombasa, Kenya. Their D77-TC Pelican was shot down by a Type-47 Scarab operating in Old Mombasa. When the dropship made a hard landing outside of Hotel Zanzibar, O'Brien was killed instantly during the crash. Private Walpole noted his death after the crash.
