the thing that bugs me most is
IF MY TANK GETS KILLED BY AN LOWBOWMEN (in a forest)
How do you drive a tank unit through a forest or jungle without roads anyways? Maybe your tank regimen got stuck and the longbowmen just starved them out of the tanks. I also always think tanks would have a rather difficult time accessing an ancient city without modern infrastructure... People never take into account that there's more to every battle than "Tank vs. Longbowman" -- its not happening in a vacuum.
