The Sturmgeschütz IV what do you think?

It seemed lower profile to me in game. IRL it’s nearly 2 feet shorter, that’s almost the height of the turret!

The rate of fire is the same for StuG & Pz. IV (20 or 18 RPM depending on cannon choice) unless you choose the 10% increase which I think makes a very minor difference.

I haven’t lined a StuG IV up side by side with a Pz. IV but I recall the profile being lower. IRL The StuG IV is almost 2 feet lower, which is significant.
