I realised that my message was a bit vague. I did, of course, saw eye to eye on his part about the tanks able to shoot without sniper view because of their 3rd person crosshair.
Weird you want historical accuracy for planes, but it seems you don't want it for tanks.Historically, all of the tanks had different gun sights some were bad some were good. Historically, gunsights aren't mounted in the gun barrel. If we did everything historically and not only when it suits you most of you would go back to arcade.
Also trying to address somebody with a point and start off like that is a good way not to be taken seriously.
