Turians running with outlaw bands have turned their mandatory military training to less noble purposes. They override the safeties on ex-military hardware to handle a higher explosive yield, resulting in deadly "inferno grenades" that leave thermite deposits on the ground after impact. The thermite can cling to armor and cause massive injuries.
APEX's largely turian volunteer force takes a dim view of these anarchists, seeing them as not only a threat but an affront to the turian values of honor and service. Those who cannot be forced to surrender are hunted ruthlessly, though this has only driven Anarchists to ever-greater feats of military engineering.
