We’ve just about cleared them out now. It’s taken a lot of effort, believe me. We’ve actually lost soldiers. It got quite a bit more difficult when they went underground: their planet is riddled with tunnels and pipes. They rise up out of the ground, attack, and then dart back down again. Since they’re so small, we can’t follow.
We’re using drones now, small enough to chase them down those holes. Some of them have nukes onboard. If we find a concentration, we send the drone down and blow them to bits.
Only a matter of time now. Filthy humans.
