Re: Let's make planes that can't fly......
Actually the M26 Pershing was a nice "Kitty Killer". Fielded late in the war but had the need been there it would have been available earlier. And the "lesser panzers" (Most german tanks where Panzer III and IV) could reliably be killed by the Sherman (Both 75 and 76mm variants). Or by the british Cromwell and the Comet.
