JD Personnel
JD Personnel
Pulled from death row, JD Personnel are basically the corporation's lab rats. They are used to conduct experiments on CTAs to uncover their anomalous properties while higher-valued staff observe from a safe distance. JD Personnel are also deployed as expendable units for life-threatening or high-risk operations that have low survival rates.
