OOC: Shore bombardment doesn't really work, on account of the size of the pillar and the fact that they tunnel. You'd have to pretty much destroy the entire pillar (~250km diameter) for that to be effective. I'd say the best way to deal with them is probably a combination of armored vehicles and infantry carrying high powered weapons (.50 cal machine guns, laser weapons, RPGs, miniguns, etc.), although no matter what you do it's going to be tough to get a foothold on the pillar.
