Oros

Second Lieutenant Oros was a UNSC Marine and ODST stationed aboard the cruiser Pillar of Autumn in 2552. She was under the command of First Lieutenant Melissa McKay and headed one of her platoons of soldiers. When the vessel was attacked over Installation 04, she, with the rest of her men, made the jump to the surface aboard a Human Entry Vehicle.

She, along with Second Lieutenant Dalu served as platoon commanders but Dalu was reassigned as a supply officer, and the position of third platoon commander was taken by Master Sergeant Lister.

During the journey back to Alpha Base after raiding the Pillar of Autumn she staged a plan to take out the Banshees attacking the convoy. She, along with a squad of ODSTs, launched a salvo of rockets at the aircraft. However, one managed to crash into the squad, killing them all, including Oros.
