Rippers were Kel-Morian Combine soldiers who fought in the Guild Wars. They made up the bulk of the Kel-Morian ground forces, and served in a frontline capacity, often coming into conflict into Terran Confederacy marines. Rippers made use of mechanized transportation such as Armored Personnel Carriers to move around the battlefield.
They wore informal black battledress, sometimes just stolen CMC armor plating patched together with pseudo-leather padding. Despite being the Combine's best-equipped soldiers, they frequently stole Confederate marine armor. Looted armor was also painted black.
Combine rippers gained glory at the Battle of Hegeron, where a gang of rippers defeated an entire battalion of Confederate motorized infantry. While the tale was likely exaggerated over the years, the cry of "HEGERON!" was still used to inspire rippers before combat.
