Lightly armored, but fast and with a heavy emphasis on flanking and melee. As they also come equipped with stealth equipment, these are basically Zudjai ninja: they can turn near-invisible to rush your position. Stay alert if you're in the thick of battle, as while other Outsiders are keeping you busy, they won't hesitate to close in while you're distracted.
Eventually, an Elite variant will also appear, with greater health, as well as shielding. Either variant: the lesser armor means a few headshots are enough to take them down.
