216 did fight in the east but only during and after Kursk with series one Brummbar.
My advice for a series three, stick to Italy and Normandy with 216 or 217, I can't remember which options you get in the kit but I'm sure both are catered for.
For your information the Dragon kit is excellent, I have thirteen of them in various guises but stay away from the series two with zimmerit, this kit
It has an incorrect roof as well as other incorrect details, the kit is very good but if you don't know how to correct it to an accurate re-worked series one it will never be right regardless of how many incorrect reviews are written about it.
Good luck with your build, its my favorate vehicle.
