Oscar Company was a Black Ops company that joined Victor and Echo as they went to assault a damaged Chimeran battleship at Orick, California. However, having deployed ahead of the main task-force, the company was ambushed and quickly wiped out by Chimeran forces, to which elements of Victor Company, led by Nathan Hale, discovered the remains of Oscar, with one member apparently split into two by a Chameleon, shortly after which Hale noted to Command that there were no survivors.
Sometime prior to the Battle of New York, the company was reconstituted and later took part in the failed offensive led by SRPA against the Chimeran tower in New York City.[1] Having taken significant losses during the offensive, Oscar was reduced to just four survivors, who desperately sought a way out of the city. Eventually, the four survivors linked up with the remnants of Victor Company, now led by Sgt. Mathison. With Chimeran Death Squads having been deployed to hunt down the unlucky survivors still caught in the city, the small band of Black Ops were forced to head to the subways to avoid the Chimera. Unfortunately for the survivors, the subways were infested with Grims and feral strains that managed to kill all four soldiers from Oscar, this subsequently left the three remaining survivors of Victor alone to find their own way out of the city.
