Ah, 442, my point I believe is valid. A fighter plane was flown by one man, and is set up accordingly. A tank on the other hand, was manned by a team. The tanker in AHII is doing the work of three-gunner, driver, and observer!

I have little trouble using the tank as abit of stationary artillery. The part I find hard is trying to maneuver and shoot at the same time and keeping orientation where the turret is facing in relation to the tank. If for instance, I am parked and rotate the turret to do some shooting, I will want to rotate it back to facing forward when if I want to roll some more, in large part becuse I know where it is and will be facing where I am going. The only way I know to see the orientation of the turret to the main body of the tank is to depress the gun all the way and rotate it abit at a time until the barrel is visible from the driver's slit. I wish there was some sort of visual indicator for this. And of course, the order of difficulty in trying to shoot from a moving tank and keep orientation is higher than stationary gunnery.
Also, effective ACM, getting very close before shooting, and flying planes with enough ammo to spray'n'pray can all help compensate for bad gunnery in the air. The same cannot be said for duking it out in tanks.
Contrary to the opinions of many, Gving is NOT easy. A funny thing happened the other day. A squad member that flies well and has been training me, went gving with me. All of a sudden he says to me over squad vox that he can't the hang of coordinating a gv. So I am thinking, no way, there is no rudder, two dimensional combat... what is he talking about? He then tells me that it is the positions. he has a hard time having to use multiple positions instead of views as in a plane. I never looked at it that way. I find having to task different positions easier than having to use all the views to get SA in a fighter. But it is simply because I have a lot more time in an gv than a plane. And vice versa for him.
