And anyone who thinks Tthe Nazis weren't capable in certain areas is completely missing the point. Technically, organisation wise, even militarily they were simply light years infront... But as I, ve said from start in other areas they were utter morons,which led to their demise... But don't forget by 1944 it was virtually a single country fighting the combined might of just about rest of world. Using fact they "lost" to discredit intelligence amongst their kind is bonkers. They wrote the book in Tank warfare (Heinz Guderian) which to this day is the Bible for tank commanders. Their war machines for years and years were basis for every army on planet. (from mg34/42 to their dreaded 88s, from their cruise missiles to their ICBMs, which they had in pipe line)
Their downfall was pure logistics stacked against them and the system that gave Hitler complete control..
It was often stated in military circles post war that using mg42 (and especially mg34, its non productionised brother) was like using a Rolls Royce as a Taxi.
Similar comparisons could be made about many aspects of 1940s German engineering. (Look under hood of a Spitfire, then a FW190) Compare a Panzerfaust with Piat gun. (a spring loaded throwing device more akin to middle ages)
That doesn't detract from the engineering prowess shown in items but does demonstrate perhaps wrong priorities for time. The AK47 used many elements from German guns, (intermediate power round, a German idea) but was shoddily, built, built to massive tolerances (to with stand grime), utterly inaccurate but cheap, quick to build, reliable, easy to use and killed just as effectively as an expensive well built gun.
