—A clone engineer
Clone engineers were clone troopers trained to operate machinery for the Grand Army of the Republic, though carried miniature bacta tanks and were qualified medics. The preferred weapons of choice the engineers utilized were shotguns, and they also carried fusion cutters for repairing items as well as miniature bacta/ammunition packs. During the Clone Wars, many engineers fought the Confederacy of Independent Systems in various units. The most notable was the 38th Heavy Armor, which CS-7934 was part of.
