Narvik touched on this briefly.
I think that part of the problem with amphib assault is more the inability to defend the coastal territories efficiently. Lets face it the Germans don’t build an Atlantic Wall to def Normandy or S France because it is too costly and inefficient. They station in Paris, let the allies land and attempt a counter attack to push them back into the sea. The only time we see a coastal territory being defended heavily is if it is a capital, major production territory or a VC.
So is the problem the attacking force is too strong able to use its bombardment then art, tanks and air units in the first round of battle; or that the def coastal force maybe should get a boost like be able to get a per-empt kill strike with its art to make it harder for the enemy to land on the beaches? Or maybe a combination?
I also like that victims of bombardment get to fire back (as others have posted). It might seem like dead men are shooting back, but in reality bombardment wouldn’t take out the entire force that a single inf represents. The greater remainder would be firing at the guys invading the beaches w/o a doubt.
