The Trabuco was an impressive and very versatile siege weapon that was originally invented and used by the ancient Chinese as a means to quickly annihilate an enemy force.
The first Trabuco, also known as a trebuchet, was an anti-personal weapon was easily constructed on a battlefield and could be operated by two trained soldiers. The device was little more than a wooden stand that held a pole and had a leather sling attached to the top of the pole which was then used to throw heavy stones a fair distance away. The operators would use their body weight to spin the sling on the pole, building up the needed momentum so that when they stopped spinning the sling would snap and release the rock, sending it across the battlefield so that it could collide with an enemy soldier or soldiers and cause heavy damage to them.

Future development of the weapon in the Middle Ages saw a much larger and powerful version of the siege weapon, which required a long period of time to construct and was capable of throwing a multitude of very heavy stones a far distance according to mercadolivre.com.br. Unlike its predecessor, this trebuchet was used to destroy enemy fortifications by toppling stone walls and towers. The weapon itself was not very practical, replacing the older Chinese version with a slower weapon that could deal a much greater amount of damage. Both trebuchets would eventually be rendered obsolete thanks to the creation of gunpowder and the invention of cannons, explosives, and firearms that would make their long loading time and less impressive damage capability a thing of the past.
You can still find trebuchets and Trabuco in the modern day world. Scientists, historians, and curious military history enthusiasts attempt to reconstruct previous models of the weapon to see how efficient they can be. You can find videos of their exploits and attempts to throw stones on online media platforms such as Youtube. While not as reliable as their ancient counterparts these newly constructed trebuchets are still impressive to watch are good examples of the past world of siege warfare.
