Remnants from the Apollo Security Team, they are led by the heroic Lieutenant Sheng. The Sec Team Survivors rally with Alpha Company and fight valiantly at their side. The group is composed of many Marines with two Corpsmen. They play the role of "Redshirts" and are for the most part expendable cannon fodder beyond the initial stages of the Campaign. Unfortunately, the entire Security Team is wiped out during the battle with Cronus.
