Sergeant Mathison was a Black Ops that was assigned to Victor Company and took part in SRPA's failed attack on the New YorkTower after the events of Operation Black Eden. His VTOL crash landed in Central Park after being shot down. He and other soldiers from his unit and from another unit, Oscar Company, survived the initial battle. A day after the failed attack the Chimera started to look for any survivors, forcing Mathison and the others to make their way into the subways. However, they discovered it was infested with Grims and other strains. Four soldiers were killed as a result. Six days later, Mathison was the sole survivor of the group and as he made his last stand in a sniper's nest in Washington Square, armed with a sniper rifle with six remaining bullets, and one hand grenade. The outcome is not clear, but it is very likely that Mathison was killed.
