After watching the old movie classic "the Guns of Navarone" I couldnt help but think about an all out naval/air assault on a large protruding Rock littered with SB's and roads for extra GV positions. One scene in the movie has Ju87's just pounding the mountain.
In Addition, if the Rock itself were kidney shaped one could place a vehicle or air base in the concave recess behind the highest peak. Word search "The Rock of Gibralter" and you'll get the idea. Its a very dynamic piece of geography.
