For the record, most tanks in WW2 were not Diesel powered, because in WW2 Diesel engine technology was not up to producing compact powerful engines that would fit in tanks. See below for videos of German tanks that killed their crews.
In any case the same things keep getting repeated, over and over again, and like the diesel-gasoline engine issue the people that parrot the same crap over and over can’t be bothered to get it right.
Perhaps the most notorious book about the incompetence of the US Army is Death Traps by Belton Cooper.
A few weeks ago I saw the Darkest Hour, the film about Winston Churchill and just how easy it would have been for Britain to just give up. One of the books that I have in my library is an abridged history of WW2 from Time Life books that has been in the family since the late 1960’s. In addition to Churchill’s text, the book has photo and art sections including some paintings from the Pacific theatre done by a man named Tom Lea. The pictures are stark in their images of the weariness and horrors of war and in showing the determination of the people involved in the war to get the job done regardless of the cost. The cost was high, as this famous picture shows.
Lea did not pull his punches as this gruesome picture of a marine’s last seconds shows.
This post from War History showed up on my Facebook timeline. It’s a small album of pictures of the Atlantik Wall built by Nazi Germany to stop an Allied invasion. The defense failed. The Atlantik Wall was a huge effort on the part of the Wehrmacht using some 600,000 workers. Massive concrete bunkers and gun emplacements were built all up the Atlantic coast.
This is a view of WW2 as the people living Germany would have seen it. It’s a false narrative, for the most part. A lot pictures of heroic German soldiers, surrendering enemy soldiers and happy peasants. No pictures of burning villages and genocide. More than a little shading of the truth and reality. To be expected of course. And not unusual when you see German stuff from WW2. As I’ve seen before.
The M6 is one of those military options that the US Army pursued and then dropped. Through 1940 and the beginning of the war the US Army initiated these various armored vehicle and self propelled gun project as stopgaps and in response to evolving doctrine. As the war progressed and these various vehicles proved to be redundant, the programs were reduced to a barely sustained level and then canceled altogether. So if the question is ever asked why the US didn’t design a heavy tank, the answer is that they did. Then the Armored forces decided that the gains were not worth the resources.
