Oh I'm sure they could write any code they want.. LOL, They could write code to make it sprout wings and fly too! But there is a historical accuracy aspect to this game ya know??
Why would they add a DD Sherman without a skirt, it wouldn't be able to swim then?
So you are saying, make it swim without the skirt, and to heck with that pesky realism thing?
And then, with a realistic damage model, while swimming, a red guy could simply spray you with a .30cal machinegun, and blub blub blub, down ya go.. That would be some easy Jeep kills.. I wonder how many perks you'd get for killing a Sherman with a few rds from a Jeep MG?
