I watched it again, I enjoyed it, but it's not Kursk.
FW-190D's (Doras)?...no
Panther A's & G's?...no
T-34/85's ...no
JdPz IV's ...no
My brother told me that he Micro-Fished old New York Times from the Sundays before the attack.
There were maps of the German/Russian positions, and they predicted (from the Germans) the "Typical" Pincer Attack!
If the Russians had no spies (which they did), all they would have to have done is read an American newspaper from thousands of miles away to know the...."Secret", "Master" Plan.

All in all not a whole lot different from the American Civil War battle of Gettysburg.
Also a determining battle as to the eventual outcome of the war itself.
The South was there first, but hesitated to take the high ground and press the attack when they had greater numbers.
They paused to bring up the rest of their army, instead of pressing the attack to gain the best ground (offering a position to attack down the line). Giving the Union (North) time to consolidate positions on the 4 high points. Not to mention, bringing up reinforcements.
When the army was ready (the South), the situation was all but hopeless. Through whatever circumstances, the South made a "Head On" attack into the teeth of the North's defenses.
I hear tell that Lee was tired of war, and wanted to "END" it one way or the other by this battle.
Hmmmm? Familiar?
And that it did, in both battles.
Not to the attackers liking, and not immediately, but the outcome was assured after the enguagement.
I have seen this scenario replayed in other, at other, times throughout history. I guess when you've had enough, you don't care how it ends, as long as it does.
Just an opinion.
