APCS

Anti Personnel Control Squadron
APCS Agents are special Agents trained to hunt down rogue and traitors. As rare as rogue agents are, they could still be a threat if not dealt with properly. APCS wear the same uniform as regular agents except with a bullet proof vest which depicts their class and behave similar to a SWAT team. They also follow the same ranks as regular agents, except the purple stripe is still present. Their appearance is seen in season 3.
