Want to warn folks, there is one picture with a German Bren Carrier with the Nazi Flag, which is one of 2 pictures, for the 2cm Bren. I could find as most models, 2D pictures depict such items.
2 variants, one has wood->Winter time. The other does not. One would be a modification similar to the snow track modification in the game.
3,7 cm PaK 35/36 auf Selbstfahrlafette Bren(e)
Panzerjäger Bren 731(e)
->You wouldn’t fire the Panzershreks from the vehicle, though I’m positive this means someone tried doing it. Meaning It’s possible that someone learned the hard way from firing it in the vehicle.
A Universal Carrier with a French 25mm AT gun used by the Germans and formally the French.
