The Republic Corps of Engineers functioned as an organization within the Galactic Republic. Their mission involved the construction and upkeep of various installations across the galaxy, encompassing both planetary and deep space locations, all intended for Republic utilization. Originally collaborating with the Judicial Forces, they subsequently provided support to the Grand Army of the Republic during the period of the Clone Wars. A notable figure within the Corps was Lieutenant Commander Orson Krennic, who served until his clandestine reassignment to the Special Weapons Group.
