Combat Team Sierra

Combat Team Sierra was a UNSC Marine Corps unit.

Background
Sierra was stationed aboard the Halcyon-classed in 2552. In the abandonment of the warship to the Covenant bombardment, the team's aim and objective was to hold off the invaders until all non-bridge operations personnel and Combat Team Alpha through Combat Team November escaped in lifepods, and subsequently, fall back to an evacuation station aboard the Pillar of Autumn. They landed on Installation 04 and may have helped Master Chief find his way through the surrounding Forerunner structures.
