Stahl Arms' Private Army is a private military organization that answers to the direct authority of Chairman Jorhan Stahl, serving more as corporate mercenaries loyal to the one who signs their paychecks as opposed to the legitimate Helghast Army and its loyalty to the state.
The corporation's private army is first seen in Killzone 3, but has presumably been around early into its history. They act as security personnel for the Stahl Arms Deep South facility, combat units in the field while hunting ISA troops, and even perform more mundane work such as firearm testing and weapon construction in the factories. This hints that the private army outnumbers non-military workers in Stahl Arms, and may perhaps have already absorbed the entire civilian body in the company.
Doctrine and Personnel[]
Pre-Helghan Terracide[]
The Private Army is not a full-fledged military force, and because it is attached to a weapons manufacturer, they employ unique and unusual forces.
HAZMAT Trooper that serves as Chairman Stahls second in command
Post-Helghan Terracide[]
After the Terracide, the private army has completely abandoned the Capture Trooper and HAZMAT Trooper, and reorganized themselves with remnant forces of the old Helghan Empire.
