Manufactured Mutiny

We don't have the firepower to dismantle their whole manufacturing operation, but what we do have is two leftover vials of anger pheromones. Let's make them count. There's a siege marshal and a quartermaster overseeing the preparations and giving everyone orders. Logistics types, but they still pack a punch. That's where those pheromones come in. Hit them with a vial, and their own armies will turn against them. Take out both, and we watch the operation crumble.
