Clone engineers were equipped with dispensers that held bacta and ammunition, as well as F-187 fusioncutters that enabled them to repair vehicles, turrets, medical and power droids. They were armed with detonation packs for sabotage and shotguns, or blaster pistols in case they had to engage enemy units. During the Phase I stage of Clone Troopers, the Grand Army of the Republic utilized repurposed clone pilots to fulfill the role of the engineer, and preformed many of the same tasks with slightly less specialized kits, many keeping their DN Bolt Casters in place of shotguns.
