What is the name of a light catapult used in warfare?

The name of a light catapult used in warfare is indeed the Scorpio. This type of catapult was designed for greater maneuverability and could launch projectiles such as bolts or stones over short distances with precision. It was particularly effective in sieges and skirmishes, where mobility and rapid firing were essential for gaining an advantage over enemies.

The Scorpio was developed for Roman military use, and its name is derived from the resemblance of its launching mechanism to a scorpion's sting. This weapon was more versatile than heavier siege engines and was often used by infantry units to provide support during combat or to defend against attackers.

The other options refer to different types of catapults or related siege engines. The Catapulta, for example, typically refers to a heavy catapult or ballista, which is used for launching larger projectiles over greater distances. The Onager, another type of ancient Roman artillery, is known for its powerful torsion-powered mechanism capable of hurling heavy stones but lacks the precision and light design of the Scorpio. Aries, on the other hand, is a term associated with an entirely different type of siege weapon and not a light catapult. This context further clarifies why Scorpio is the distinctive answer for a light catapult
