What is the Cockpit Option in the Graphics Options?
If you had looked at a few of the enhanced screenshots for Battlezone you would have noticed that some of the screens seemed show the gun of your tank as you might see it through the glass of your vehicle. When you enable the cockpit in the grapic options that is what you get. Some may find this better as it seems more realistic while others may wish to have the full screen available for surveying the landscape.
