Thanks for that ... this is the fun part of coding. I will be using the current King Tiger size as the standard and scale all other land units accordingly. For Ship scales, I will use the current "Bismarck". For Planes I will use the Me109, albeit significantly smaller than it currently is in order to be able to scale the bombers correctly. So each domain (land, sea and air) will have their own scale. It would not be good to try to scale seperate domains.
