Tank Destroyers. Yes! Concept was light-skinned but up-gunned tank destroyers would be fast to where needed to deal with enemy tanks. During my time in the army, the tank destroyer was supposedly succeeded by the TOW anti-tank missile. In the constant leap-frogging of tank design, modern tanks used composite armor and stand-off to defeat the shape-charge in missiles. So, today, it’s just about the case that it takes a tank to beat a tank. From what I can tell from a youtube video, the tank museum at Danville is quite impressive.
One fine article.
The 2nd and 3 rd Armored Divisions were heavy divisions and had 60 or 70 more tanks than the other divisions and did a great amount of the fighting after the invasion which I reckon is the reason Ike queried their CGs.
