Noticed the other night when I took an osty into a town to level it...There's one building in town that seems to take a huge amount of ammo--it's a little warehouse looking thing on the side. Spent like 200+ rounds on the thing and it just laughed at me. Probably put there on purpose to discourage exactly what I was doing, but...
Does it require a bomb? A bulldozer? Couple of 75mm rounds of HE?
