Those cities were completely destroyed. I’m sure we’ll find out how that will effect things I the near future. For now, we’re standing by for the next Major Order. I wouldn’t be surprised if the first order of business is to harvest E-710 to fuel reconstruction, or to push out the predator strain planets that have gotten closer to Super Earth. I haven’t seen a lot of activity in terms of movement on the bot front while the defense campaign was ongoing.
You either have to hammer the main neck joint, or you expose a weak point with anti tank (wings, engine rings) and then heavy pen can follow up. Keep hitting the exposed area, and they’ll drop within 6 recoilless rounds, 4 spears, ~10-14 anti tank shells, or 2 recoilless and whatever you follow up with.
They aren’t really worth the fight, but we’ll see what the future holds.
