The set includes 2 large ballistae (bolt-shooters) plus 9 models (1 officer and 8 crewmen). A mixed combination of helmets are supplied. Each cohort in a legion is equipped with such a bolt-shooter with crews drawn from among its ranks rather than having a specialist unit. The bolts traveled at such a high velocity that they were capable of impaling more than one enemy. (Use "Gorilla" Super Glue.)

The ballista (Latin, from Greek βαλλίστρα ballistra^[1] and that from βάλλω ballō, "throw"),^[2] plural ballistae, sometimes called bolt thrower, was an ancient missile weapon that launched a large projectile at a distant target.

Developed from earlier Greek weapons, it relied upon different mechanics, using two levers with torsion springs instead of a tension prod (the bow part of a modern crossbow), offering much greater efficiency over tension-based weaponry. The springs consisting of several loops of twisted skeins. Early versions projected heavy darts or spherical stone projectiles of various sizes for siege warfare. It developed into a smaller precision weapon, the scorpio,^[3] and possibly the polybolos.

The ballista was a highly accurate weapon (there are many accounts of single soldiers being picked off by ballista operators), but some design aspects meant it could compromise its accuracy for range. The maximum range was over 500 yards (460 m), but effective combat range for many targets was far shorter.

The Romans continued the development of the ballista, and it became a highly prized and valued weapon in the army of the Roman Empire.

It was used, just before the start of the Empire, by Julius Caesar during his conquest of Gaul and on both of his campaigns in subduing Britain.During the Empire period, the Scorpio was used extensively for offensive and defensive purposes.
