This tank variant will likely not work due to mod issues, but I'll tell you about it anyway.
This tank is controlled by two crew members: a gunner and a driver.
To control the driver, find the hatch in the front of the tank and take the controller from the lectern. Then, press the joystick on the tweaked controller hub located at the back of the tank. Place the controller back on the lectern and control the tank.
Forward - W
Backward - W+R
Right - D
Left - A
For the gunner, you'll simply need to sit in the seat located in the turret (use the camera for easier aiming). However, your tank will likely have a separate turret and no cannon (I don't know why).
Don't forget to fill the tanks with diesel and the blue engines with carbon blocks.
