The modified tanks have been fitted with strong armour, which you can appreciate using activation group 7, and the rapid-fire guns can now attack in the air, and the problem of blow-ups has been improved as well! It's a special tank,because it can be driven on land or in water.When you're driving on land, just hold down Roll to move,hold down Yaw to steer.When you are in the water, use the throttle to control the VTOL to travel through the water and Yaw to control the direction.Don't try to use VTOL on land! The tank has a powerful main gun and two rapid-fire guns, both of which can be used on the ground or in the air, and can be controlled horizontally via VTOL or vertically via Trim.
