This is mostly for Keith, who was asking about the download over on
BGG. I suppose the rest of you can join in if you really, really, really, really want too.
Anyway, Norm Smith had this unit to work with:
If you follow the nomenclature, it is really a
leichte Schützenpanzerwagen (3.7cm PaK). Obviously not SPAA.
The new counter is this:
The problem here is that the SdKfz 10 was unarmored. Essentially a 1/2 truck.
That is why in the reinforcement note for that unit says that it is probably the SdKfz 251/17, or less likely they SdKfz 250/9.
So that is the back of the back story.
Side note: The SK 10/4 in Burning Tigers & Liberation '44 should technically be unarmored, or be renamed SK 250/9.
