Here's my reasoning:
Mass assault doctrine is almost always bad unless you're either an Asian nation (I'm including Russia), or you're a large nation relative to all others on your continent and are going for a continent conquest.

You'd think the Grand Battleplan doctrine would be the best if you are only starting off by puppeting Italy, but I'm going to take all of the Balkins and the Holy land before I take on NATO, meaning there shouldn't be too much of a problem, so shouldn't that be just enough to go either Superior Firepower or Mobile Warfare?

Superior Firepower might not be best as I still might not have enough territory to build enough factories to make it all worth it.

I have much experience with Mobile Warfare and am good at micro-managing units for encirclement. Aside from skill, would this be usable?

What do you all think?
