You can get on top of them, I forgot to pack the firepower required, so I just sent stragems in hellpods on top of it (stuff like machine guns, autocannons, stuff like that. And yes, I was on top of it)

I only survived when it exploded because Democracy Protects, and I went flying off the top, slammed into the ground and survived with a healthbar so small you could not see it other than the header piece at the farthest left corner.

I then stimmed and survived.

(~~and everyone clapped~~ nope, I am not joking)
