Im going for Combine Overwatch, most of their weapons are way more high-tech( gravity gun can push bullets back at their attacker and The pulse rifle is a devastating energy attack.), plus most of their batallion consist of aliens and alien hybrids which gives them a superhuman edge in close-quater combat.
