Steve,
I have a problem with the Commonwealth Armed Forces, since you've left out First Cavalry, First Armored Divisions , and Third Infantry Division (Mech)--The Rock of the Marne is a very proud Division in US Army Lineage, as is the Golani Brigade in Israeli Lineage. I can see Giving the Commonwealth another Corps, as I would the Chinese and Terran Union.
Also, I think you left out the Indian Divisions nor given the Chinese a large enough army. I would hope to see more Russian Guard Tank Divisions given their role in World War II.
China and India with two plus billion people can raise armed forces larger than what you're showing. Not significant but just an observation
Terrible being a military historian, I know its just a game but.....

All the ground forces have far fewer units than they would have in reality, just as the space forces are far fewer in number than current navies. If I had included every current division for every major world power, there would have been hundreds of divisions in the game. My experience has been though that if you triple the number of units in a game, you triple the management requirement but you don't triple the enjoyment. I am trying to provide enough units to create a flavour for ground combat without having huge number of divisions. I would also had to reduce the supply requirement of all the units to accomodate more of them
I could have used the Corps as the base unit instead of the division but I think players identify more with well known divisions than corps. Also with fewer units, each one is more meaningful. You may be concerned about the fate of the 101st Airborne, one of only four assault infantry divisions, but you wouldn't be concerned about it if you had twenty of them (or fifty)
In any event, over time the powers will build more units as their empire expands and the divisions that you named will come into existence.
By the way, the I Armored Corps includes the 1st (US) Armored Division ARM-3 and the 1st Cavalry Division ARM-3
