How to deal with the drill mech?

[tetleytea]

Actually, I didn't use 1 tank and all ranged units. For the Driller I like Droids the best (you are, after all, on Montero). You can hit him with the guard droids all you want, just as if they were a summoned unit--you are, after all, going to repair them all anyway. And there's no reason the Driller should ever hit the repair droids. Plus with the repair droids' speed they have no problem getting out of the way of the collapsing tunnel.

I was no-loss completely by accident, so I imagine Pallies + Droids would scale to Hard etc. without too much problem. I could have filled the remaining two army slots with anything (well okay, almost anything: speed 1 units would not be too wise).
