Good new for the Super Pershing cry babies (like myself ;P )!
Super Pershing with the garage is the SD version (from before 0.9.8),
the other is HD. The armor displayed is without spaced armor. As you can
see the previous one had a huge space behind the turret (green zone)
while the new one has that space covered by armor (completely
unhistorical) so the turret got in theory a massive buff.
