Riot Security Guards are a more heavily armored version of the ATC Security Guards, and are capable of going head to head with Replica soldiers, despite only carrying light weaponry. They have enhanced health and armor, which makes them more durable then most Replica soldiers, and are only slightly less tough than a Replica Elite Soldier. A Riot Guard can survive a direct hit from a frag grenade, or even a shot from the Type-7 Particle Weapon. The Riot Guards, much like all ATC forces, are not seen after the Origin facility explosion.
