====== Chain Gun ======

A chain gun is a type of machine gun or autocannon that uses an external source of power to cycle the weapon rather than diverting energy from the cartridge, and does so via a continuous loop of chain similar to that used on a motorcycle or bicycle. "Chain gun" is a registered trademark of Alliant Techsystems Inc. for a chain-powered weapon. ([[https://en.wikipedia.org/wiki/Chain_gun|source]])
