Chaos drone

The Chaos Drone was an unmanned vehicle within Yuri's arsenal.

Like many of his forces, it made use of mind control but in a completely different method. Instead of trying to control its enemies, the Chaos Drone does what it name suggests and releases a hallucinatory gas which causes enemeis that are exposed to it to behave violently even against their own forces. This allows a well ordered enemy column to collapse as the gas amplifies the strength of the affected enemy who end up attacking their own comrades before attempting to fight Yuri's forces.
