Ok, w.e. Let the tank be at the highest point of the map. And its totally understandable that hangar can hold that weight :D. And no, it cant be destroyed cause its only rare situation that both sides of hangar have that kind of firepower at the same time. And no, its very easy to repair, squad member dies while repairing, he respawns in tank and continues. 2 tanks were on hangar with 43 and 36 with 0 deaths. Axis got totally wasted. Even if tank gets destroyed, it will go there back again. The problem is, theres not much places to take cover.
