Christian - 168, is the heavy hitter of the team.  Spartan 168 is in charge of demolitions,  he can disarm explosive devices and carries the tools for that in his leg pouch.  He also has a knack for making things go BOOM!  He carries 2 plasma bombs, much larger than plasma grenades, and a large double barrel machine gun turret with a standard issue shotgun for close range combat.

Alyssa - 175 is the sharp shooter of the team.  She attains high ground and eliminates any hostiles that pose a threat to her team.  Her armor has been reworked lighter and she has been given a short range flight pack to get her into those superior sniping positions.  Her sniper rifle is a highly advanced prototype based on covenent technology, both the flight pack and sniper rifle are directly wired into her nervous system and AI unit.  She also comes with a frag grenade and shotgun as well.
