A siege weapon is a type of military equipment designed to break or circumvent fortifications during a siege. These weapons were commonly used in ancient and medieval warfare to attack castles, city walls, and other defensive structures. Examples include the catapult, trebuchet, and battering ram, each serving a specific purpose in overcoming obstacles. Siege weapons often employed mechanical principles to launch projectiles or apply force. They played a crucial role in determining the outcome of battles, as they allowed armies to breach defenses and gain control over fortified locations. The development of these weapons significantly influenced military tactics throughout history.
