German player receives "1 tank." What kind of tank?
Unfortunately in the original PDF there are no details about the tank.
In the scenario on Vassal I have arbitrarily added a Panzer III (for the simple fact that it is the only one in the field).
It surely need some playtest.
I would humbly propose this be a standard Pz IV unit. Not knowing the date when this scenario was created, because the type of tank isn't specified my default would be to assume the designer was using the base game before any of the expansions. In this context, "1 tank" for the Germans would mean the base Pz IV.
