Cairo Station Security B-01
Cairo Station Security B-01 was the United Nations Space Command portside security station of Cairo Station farthest from the bridge. During the Battle of Earth, Covenant boarders invaded the security station, killing all the Marines. They then set up a portable Plasma Cannon and used it to wipe out the Marines in Commons B-01 below. John-117, however, killed all the Covenant present here on his way to find the antimatter bomb.
