The heavy catapult was a powerful siege weapon, representing the greatest advance in siege weaponry during ancient times. It was employed against fortifications and on the battlefield. It broke down fortification walls, allowing attackers to break in. On the battlefield, smaller missiles could be fired in a shower against dense formations of soldiers to cause casualties and disrupt morale at long range. Enemy armies that could be softened and shaken before the hand-to-hand clash of infantry were at a decided disadvantage.
