Ok, looks absolutley amazing! Love the plane idea too! 2 more questions now.
1st, unless you just haven't added them yet, where are the hedgehogs and the log ramps? Having only the LTV's won't provide enough cover beause if everyone hides in an LTV, waiting to move, the eventualy the defenders will start throwing grenades in there and killing everyone inside. Nice idea too to have the mortar fire on the defenders because actually, there was in the real invasion as well. The Allied destroyers just off the shore were bombarding the cliffs with shells. Oh, theres still gonna be mortar fire on the beach right?
2nd, are the concrete bunkers (towers) actually destroyable, or is that like that so that the defenders dont have 6 HMG's? Because 6 might start to be too hard, whereas 4 (like there was in real life) would be a lot better.
