Anyone serious (outside of "history" channel documentaries) ever said the entire US AT arsenal was ineffectual?
That being said, Arracourt etc. which you'll often find quoted as a vindication of US armour doctrine/employment is a problematic example at best, as the newly created German Panzerbrigaden that made up the bulk of the German forces were hastily shuffled into action and proved clear organisational failures, way too light on combat support/logistics and even more importantly, virtually untrained. In fact, most German crews could hardly operate their tanks individually, let alone function and fight as a formation. This was exarcerbated by the fact that for the most part they were commanded by men who lacked Western front experience and completely underestimated the organic firepower of US formations and the impact of their aerial support...In a way a similar situation to what the Soviets experienced in 1941 on a far larger scale.
As for IS-2 reload, balance&gameplay over authenticity any day IMO.
They play documentaries on the History Channel? I thought that was for Reality TV...
On a more serious notes I am talking about various books I have read on the Subject. Some from German perspective and a very interesting research paper a retired Lt. Col wrote for his Masters Degree about the P47 and how they would literally "Kill" more Panzers then there actually were in the area thus showing that the rockets werent as effective as we thought they were.
Other then Artillery reforms the US did in the 30s everything I tend to read is it wasnt as good. Yet the fact of the matter is the US inflicted significant losses on the Germans none the less. A study on the US fuse systems used in the 105MM Howitzer were proven more reliable and devastating then the German artillery but even the GIs in the war believed the German artillery was better.
I find it rather comical.
