OVA
Description
O'Brien, a human Orbital Drop Shock Trooper in the 105th Shock Troops Division, fought in the Human-Covenant War as a sharpshooter under Master Sergeant Cortez aboard the UNSC *Kronstadt*. Standing 177.8 cm with red hair and blue eyes, he harbored fierce pride in his marksmanship. During Operation: GREY VEIL in 2544—a covert strike to eliminate a Covenant Prophet overseeing Heian’s logistics—he chafed as backup sniper to Spartan-II Cal-141, considering the assignment beneath his expertise.
His SOEIV drop pod plunged into a methane swamp during the insertion, its oxygen tank ruptured by meteor debris. Though Cal-141 saved him by wrenching the submerged pod free, he met her aid with seething defiance. Throughout the mission, he clashed with Cal, openly质疑 her judgment and dismissing her repeated rescues, even after she intercepted a Jiralhanae chieftain’s gravity hammer strike and recovered him from a crumbling waterfall ledge. The loss of squadmate Checkman during atmospheric entry further fueled his bitterness.
When Cal sacrificed herself to shield him from the chieftain’s final ambush, O’Brien reluctantly took her position. Hesitating only briefly, he neutralized the Prophet with a single shot. The sight of Cal’s unhelmeted face in death—stripped of her Spartan armor’s anonymity—left him grappling with unspoken guilt. He withdrew post-mission, avoiding debates over her legacy.
By 2559, his tactical decisions on Heian, particularly the Prophet’s assassination, were archived by UNSC strategists on the Ark, analyzing his methods to refine strikes against Banished leadership during the Second Ark Conflict. His service record remained devoid of further commentary on Cal-141.
