In the first game, no part of the tank interior is actually modeled, What would be awesome for Heroes of Stalingrad would be to have a fully modeled tank interior, which to get out of/switch positions, you actually need to go through a whole animation that involves your guy clambering through the hull of a tank. This would add to the immersion immensely, IMO, and also prevent 1-man tanking from being so effective. Plus, no more tank crew jumping out of their tanks instantly to shoot a rifleman hiding at the side of the tank.
