Carroballista

Cart-mounted ancient siege weapon

Carroballista was an ancient, cart-mounted ballista, a type of mobile field artillery. According to the Roman author Vegetius, each legion had 55 carroballistae which were arrow/bolt-shooter of the cheiroballistra type. Vegetius tells us that each carroballista was carried by mules and operated by one contubernium.
