It would be great if tanks, apcs and attack helicopters had a targeting system like the airborne drones do, except it is a system you can turn off or on depending on the situation. In the game at the moment, if you are aiming in a tank/heli/apc that is moving, you have to manually keep the cross hairs on the target. I propose that you install the targeting system on the airborne drones (which automatically keeps the cross hairs still wherever you point them)on the aforementioned vehicles in order to maintain a more realistic gunning experience. However, this needs to be a system you can turn off or on in battle so the gun does not turn to keep the cross hairs on a piece of ground you were accidentally aiming at.
