Chaos Drone

"Uh-oh. What's this? Chaos Drones? Well, that must've been so deadly by now that Yuri built a lot of them, as ordered all by himself."

--Su Ji-Hoon, Drones of Chaos

A Chaos Drone is an unmanned vehicle within Yuri's arsenal.

Background
Like many of his forces, it made use of mind control but in a completely different way. Instead of trying to control its enemies, the Chaos Drone did what it name suggests and released a hallucinatory gas which caused enemies that were exposed to it to behave violently, even against their own forces. This would cause even a well ordered enemy column to collapse as the gas amplified the strength of the affected enemy, who would end up attacking their own comrades before attempting to fight Yuri's forces.
