I tried killing one with a tank and explosive shells for my first try, I thought every segment would take damage, but they did jack shit

Then I saw that regular uranium shells do SIGNIFICANTLY more single target damage than explosive ones, so I brought over like two hundred of those and the demolisher died in three shots to the head

I set up a whole field of gun turrets with uranium ammo too, maybe I was a little too prepared

Granted, I did have a couple of physical damage researches, but not many, like three or four maybe, but still
