Oros

Second Lieutenant Oros was a UNSC Marine and ODST stationed aboard the cruiser in 2552.

Background
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. Lt. McKay did not know about her strategy, but Oros continued anyway. Oros' squad of ODSTs left their Warthogs to find cover in a clustered, rocky hill. They launched a surprise salvo of rockets at the wing of enemy Banshees approaching the convoy. All of them scored direct kills except for three surviving Banshees. The two broke formation and retreated while the third mortally wounded aircraft plunged into the rocks where Lieutenant Oros' squad was hiding, engulfing them all in a deadly explosion. All Marines including Oros in the squad were presumed KIA. If any managed to survive the banshees' suicidal feat they would most likely have been killed either by the covenant, the flood or the destruction of installation 04.

Trivia
