The United States has received an amphibious assault vehicle class, to give you some armor to storm the beaches with your marines (Note this is unique to the US). In Vanilla, heavy tanks were not worth producing because they costed too much and medium tanks were simply so much better. Heavy tanks are what they should be - expensive and immensely powerful. There is a clear progression in the development of armor. With thin armor and small guns, tanks were largely infantry support vehicles in the early war. The early war has been tweaked, armor is what it was - weak. For example, Italian tanks were cheaply made, but they were not mass produced therefore I couldn't use the historical production numbers and made them more realistic for what the tanks were. This mod is largely historically based, so not everything is balanced, as war is not balanced. Screenshots above are me observing the AI! The AI will fully research and recruit the custom units and tech. Each tank is 100% unique and a Panzer IV no longer has the same stats as a T-34! Features Starting with an armor overhaul, all of the major nations (the big 7) have received customized armor / vehicle tech trees and units.
