Watched a panzer get hit with about 8 500 pounders last night and survive. One of em bounced off of him. I shot the same panzer 4 with about 8-10 40mm rounds and it finally died. A tiger soon after was the same...almost. I shot it with a few 40mm saw penetration but no damage. Another fella hit it with some 1k eggs. I finally got a ju87 and hit it with a 1000kg bomb and he died...is this a bug or feature?
