Cairo Station Hanger A-02
During the First Battle of Earth, Hangar A-02 was invaded by Covenant boarders. A Covenant Boarding Craft had docked and was sending forth waves of Grunts and Elites. Marine defenders were overwhelmed and forced to retreat to the mouth of the bay, where several soldiers equipped with Battle Rifles were under suppressive fire from two Plasma Cannons manned by Heavy Grunts]]s on the second floor of the hanger. Spartan-117 then arrived from Hangar A-01, bolstering the Marine forces. The group was able to kill most of the Covenant boarders and force the survivors to retreat back to their landing ships.
