Thank you Door_a_jar!
However, I usually play as the tank driver because I don't find the AI driver good enough. Also, I find the AI doing a better job than me with the commander's turret. As the commander you have a sight, but as a driver you have the same problem as in a helicopter.
Another question. When playing as a helicopter gunner, is it possible to stabilize the sight on one ground location so that you don't have to compensate when the pilot moves the helicopter? As a tank gunner, the turrent rotates automatically as the tank rotates to always point at the same spot. As a helicopter gunner with an AI pilot who doesn't understand that he has to keep the chopper stable, I'm in trouble.
