They look very nice.
Since you have CoE and FR, I'm sure these guys will be very busy. Here are my notes on a couple of the unique counters:
105mm/L11 Mountain Howizer
This is a very light weapon for its caliber. It is draggable and may be towed by jeeps, kubelwagans and Motocarrelli.
Motocarrelli
This is a motor-tricycle prime mover. It may transport any gun a jeep/kubelwagan can. Being a prime mover, they may not be used to carry personnel. The Italians used them for transporting light guns and supplies.
As a general note: I mark draggable guns with a black 'T'.
