OK so that's 3 more models to work in for light tanks, and probably some armored cars. I also had the thought of having the later main battle tanks also create new heavy tank brigades, to give a firepower boost on the brigade level. Some notes -- the militia will be enabled EITHER through the infantry OR the guerrilla warfare tree(earlier through guerrilla warfare!), so the 6 militia can stay as a 2012 model that only comes from the guerrilla warfare doctrines. The reason for not having the baseline M1 Abrams for the US is that it does not have the main gun that all the other models have. Would you like to suggest a "less boring" USA tank tree? OK I'll do Israeli airpower while I work on Vietnam. Israel should get British models to about 1951, British and French models to about 67 and USA plus homemade stuff after that IMO (West German submarines). Italy is a ways off but I might as well discuss the naming issue. Italy produced only a few indigenous models and imported the rest, both from the US and West Germany. I believe that they get BOTH the West German and US names with a slash, as is done for the USA carrier based planes, and use either the German or the American model for pictures.
