The fort's inner and outer walls were separated by a distance of 50-70 meters, dictated by the natural terrain. The inner wall was manned exclusively by expert archers and equipped with a few catapults, while the outer wall hosted a diverse mix of archers, spearmen, swordsmen, and additional catapults.
Between the walls, the space was occupied by reserve military units and civilians handling logistics. Serpentine stairs connected the outer walls, often forming descending secondary walls at choke points. These stairs featured broader spaces and proper boundary walls, enhancing the fort's defensive capabilities.
