There are a bunch of new players around, and I'm still learning having only played for a year and a half or so... in fact, even the older players are learning since there's a new mod.
So I'd like to start with unit composition and opening turn strategy for nations (in general and specific). First, no design is 'the best' (at least as far as I can tell. Each style has its own assets and hinderance. But I will say that A design is key to having a good force... some discipline is better than none.
For me, a general rule of thumb is condensing units in Turn 1. This gives 'free' PP to use in technology. For Germany, France, Japan, and China. This easy PP is especially key as all these nations are in medias res of war or rapidly approaching it.
I can't speak on all the nations since I've only been Japan, China, Germany, and the Soviets.
As far Germany goes, I think Rifle II is key in the 1st round so you can use supplies before they spoil. Also, I have found Armoured Car II is fantastic. It gives you a great weapon that's better than any German tank and is great on fuel. Also, they will serve you for years to come.
I'll start here and see if this thread flies... any and all wisdom is appreciated... I really like to win
