Roman army had at its disposal several types of artillery

. Here however we will look at he two types used by LegiiAvg.

We have a

catapulta and a ballista

. The ballista is a stone thrower and ours is capable of firing a stone the size of a cricket ball whilst the catapulta fires a bolt. Both artillery systems are torsion operated. Each piece has two skeins of rope, each twisted under pressure and held in tension by the bow arms. It is that tension that throws the bow arm forward and hurls the missile towards the target.

Each legion would have 60 piece of artillery at its disposal
