👉 An arch weapon is a type of ranged weapon historically used by various cultures, notably the ancient Greeks, Romans, and various nomadic groups. It typically consists of a curved metal shaft attached to a stone or bone point, allowing for powerful and accurate long-distance attacks. The design enables the user to draw back the bowstring, store energy, and release it swiftly, propelling the projectile with significant force. Arch weapons were favored for their versatility, ease of use in different terrains, and the ability to engage targets from a distance without close combat. Examples include the Greek salamis, the Roman pilum, and the Mongol khopesh.
