Maybe you can add it like a kind of Mountain, so it is undestructable like in real and you can add the guns on it easyer.

Hmm... yes, in RL those Flakturms was hard to crack, and already are. But it would be very cool, if you can see
some surface destruction, when it get bombed.

Anyway, looks very authentic, well done... hope you can get it into game.
