ammunition Grille upgraded with 30mm flak 103 (Kampfgruppe Milowitz, this vehicle destroyed the Prague old town hall, due to the weapon high elevation, photos in MBI book Marder & Grille)
Sd.Kfz 234/3 with 2cm Schwabelafette (20.panzer division around Pilsen, photos in Panzerwrecks 4)
Pz.IV with 88mm flak 36 (Pilsen - Bory airfield, photos in Panzerwrecks 10)
Bergepanther with 2cm and 3,7cm flak
TACAM R-2 (Romanian army, Brno)
next:
Sd.Kfz 251 drilling
and Pz.I with Stuk 40 (both in Berlin 45)
Or s.Pz.Jg.Abt.653 near Wasaw 1944 has also very nice mix of unique vehicles:
Tiger (P)
BergePanther with Pz.IV turret (turret not rotable)
BergePanther with Flakvierling (turret rotable)
Flakpanzer T-34 with Flakvierling (turret rotable? I am not sure)
Ammunition Pz III and T-34.
BergeElefant (all info and photos in Stackpole book Combat history of s.Pz.Jg.Abt.653)
I have almost all these vehicles as 1/35 Dragon model kits, thus sources are sufficient.

Is it difficult to make these modifications? Which program should I use? And how to implement them into game? Thanks in advance
