Germany's Panzerkampfwagen IV, SdKfz 161 medium tank updated

Now that I'm back to updating the vehicle pages, I'm trying to better organize them and rewrite some of them to make more sense. Thus updates will move along, but just won't be as many as there was when I was just adding planes.

I've now made updates to the PzKpfw IV. Specifically the PzKpfw IV Ausf F1, PzKpfw IV Ausf F2, and PzKpfw IV production.
