During the Battle for Earth, his squad was dispatched from the In Amber Clad to relieve Marine ground forces fighting the Covenant invaders from the Fleet of Sacred Consecration in New Mombasa, Kenya. Their D77-TC Pelican was shot down by a Protos-pattern Scarab walker operating in Old Mombasa. When the dropship made a hard landing outside of Hotel Zanzibar, O'Brien was killed instantly during the crash. His death was announced by Fones.
O'Brien was named after Bungie employee William O'Brien, who worked on the animations and cinematics for Halo 2, including Another Day at the Beach.
