I checked out the book called "Kursk: The Greatest Battle" which is on the Books and Resources list on the sub, but i saw that it only has four reviews on Amazon with one of them saying that it's only an introductory work, and the other calling into question the facts stated on it. So i was wondering if there were any other alternatives out there.
I can confirm that Kursk: the Greatest Battle is a good book, it has a few bits and pieces that could be better. But its a solid work none the less. However another good book is Armor and Blood: The Battle of Kursk by Dennis Showalter.
You can't go wrong with either one.
You may want to have a look at Kursk, the German view by Steven Newton. It is what it says the German view and includes German plans ahead should they have prevailed.
