A simple solution to this might be to allow the LST in the game but not allow it to land vehicles unless the nearby base is dropped to a certain level (i.e. nor ord, no radar, no troops, etc, etc). This would represent the fact that LST's did not land and drop their vehicles until a beach head was established. I know this is not the nest solution if at all a solution but it may open up other ideas to this concept but still keeping it histoical in the fact that LST's did not hit the beach until after assualt troops had cleared the beach and moved inland. LST does stand for Large Slow Target!!!!
