Officer (COM): "Raven Actual, we're tracking your descent onto the surface. Current vectors are within acceptable range. We need you to get as close as you can to the Pillar of Autumn's LZ and help establish a defensive perimeter. Stand by for vector coordinates and convoy rendezvous point. You're going to encounter immediate Covenant resistance. The Autumn must not fall into enemy hands. No matter what it takes. Good hunting, Fireteam Raven."
