But the Roman Legions didn't use trebuchets. They used catapults. One of the advantages of the trebuchet over the catapult is the lack of jump (which poses a major hazard to the weapons crew: historically, about 1/5 to 1/4 of the catapult crews were eventually injured or killed buy their own weapons) when the weapon is triggered.
