Yep, apparently even LAWs and RPGs can make just a small hole, if you need to make an alternative entrance you need either heavier ATGM warhead (Javelin vs Mud Hut, way to go! ) or 105-120mm tank gun. It is possible to get through with a .50 HMG, but you'd better reserve few hours and a convoy with ammo...
