The ballista "Raven" had a tennis ball taped to it's beak because the beak violated the "half inch" rule. It could penetrate a face grill more than a half inch.
The ballistae brought by Baron Jonathas, Atlantian Siege DEM. In the fort battle, he didn't shoot his own ballistae, but commanded them instead. They were used very effectively.

I liked the balance on this ballista. It's easier to move than mine.

Doc Mo's powered up ballista which he brought for the history channel shoot that was canceled. It was the only one which failed inspection because it fired a bolt 150 yards; well beyond the 80 yard limit. Notice the recurve on the bow; this gives it extra power. It also has a ratchet, geared windlass, and an elevation crank.
