Kursk was a campaign, that included several of the largest tank battles, including Prokhorovka. German vs Russian, July 1943. So Kursk and Prokhorovka are reffering to the same thing.
In the West, El Alemain (N. Africa 1942), Normandy campaign 1944 (not just D-Day), and the Ardennes, 1944 would be three to look at.
