Emperor Taiki
I quite like most of your suggestions with a few exceptions
1.) Id prefer a Wespe, or Hummel to the nebelwerfer, but that’s a pretty minor niggle
2.) Panzer II. Id rather we had panzers IV & VI to go with the AA50 V’s
3.) ME262. No other recognizable plane than the Ju87 and the bf109? What about the FW190?
4.) Ju390, prototype only aircraft don’t really fit for me. He111 or Do217 probably better fits.
5.) Il-2 isnt really a fighter, one of the late model Yaks or a mig would probably be a better fit.
Just my 2 cents
