Battle Group X-Ray

UNSC Battle Group X-Ray was the first fleet given to Admiral Cole to attack the Covenant at the Second Battle of Harvest in March 2526. The fleet engaged the Covenant over Harvest, and due to a last moment of tactical inspiration on the part Admiral Cole, Battle Group X-Ray managed to destroy the Covenant super-battleship in orbit. The battle group was disbanded or transferred to another flag-officer sometime prior to the Battle of Psi Serpentis, as Admiral Cole then commanded UNSC Battle Group India.
