Combat Team Alpha was a UNSC Marine Corps unit.[1]


"Alpha" was stationed aboard the UNSC Pillar of Autumn in 2552. During the abandonment of the warship, it was to hold off the invaders until all non-bridge operations personnel escaped in lifepods and then retreat to an evacuation station aboard the Pillar of Autumn during the Covenant boarding action. Combat Team Sierra through Combat Team Victor evacuated after them.
