I would say that we are all on the same track. The Russians made a plane that could survive all weather and be all shot up, Il-2, the Americans would try to make it a little to pritty and nice, the P-51 a good example, but the b-26 was an over all good plane. Why must we limit tank killers to fighters? The Il-2 was not a pure fighter, we could make the case for the Pe-2 and its veriants.
Aircraft of the WW2 theatures were for the mostpart able to adapt to different operations and missions.
