Not a battle but would like to have a career mode. But as for a battle id like to see the battle of Brody.
Battle of Brody, 23 – 30 June 1941
The Battle of Brody, which has been called “the largest tank battle of World War II until the Battle of Kursk two years later,” saw 800 Axis tanks line up against 2,500 of their Russian opposite numbers. The German victory was partly due to their air force, the Luftwaffe, flying over the Polish war fields, destroying up to 201 Soviet tanks. However, the tank battle was incredibly fierce, with the German forces finding that the new Soviet T-34 tanks were virtually impervious to their firepower. It was mainly due to the Red Army’s supply chain drying up that the Germans were allowed to continue their offensive and press home their advantage.
