In the level, the 22nd answers a hail from the Amber Clad, assisting the UNSC in repelling the Covenant forces from the population centre. The 22nd eventually participated with the Army's EVAC battalion, assisting the infantrymen in evacuating the mass population of civilians and joining the SOARs in destroying key Covenant installations.
