Yes you're right. With a side note:
- for smaller countries the firepower per unit is more important.. playing with Netherlands or Belgium I usually lack the amount of people..
- playing larger countries you can simply just pull out 1.000.000 out of the reserves without a big problem .. so for them
I think the only matter is firepower/ USD
-and between smaller and huge countries it's both.. finding a balance in
firepower/unit and firepower/USD
So you are absolutely right, it's about finding the proper settings for your country on firepower, units, USD
still the K Panzerkampwagen just WAY out of the others.. it's just disproportionate
