Aswangs (Boarding Shotgun) by Corvus Belli
In layman's terms, they can devour living enemies to heal themselves or become more resistant. This ability allows them to operate in enemy rear echelons, feeding off enemy supply lines and field hospitals, turning them into fearsome adversaries. Amongst human line troops, news of this special unit's voracity spread quickly. The PanOceanian troops call them Aswuangs, a vampiric creature from Philippine folklore that eats human meat.
