@DrLarsen:
a. You’ve got uniform sets of rifle-stand infantry in 5 categories:
          i. rifle—14
          ii. SMG—6
          iii. AR—3
          iv. MG—6
          v. ATRL—3
[OK, so far so good, assuming I’m willing to give rifle-stand infantry a chance, I think I can come up with 5 types of infantry units…]
b. But with the tanks… is it supposed to be two size levels or three?
     c. Are you thinking a distinction between standard tank and TD?  But not all powers have a TD, and the ones that do have them in differing sizes…?
I can sure tell you are an author.
I started tooling 4 years back but then lost my job and put this project on hold.  The whole new A&A with the super size board was not on the radar back then.
The 14 rifle would have replaced the standard infantry in the regular game.  Then I figured players would add different types of infantry as the game went on.
I used prints that I believe are the same scale.  I scaled my tanks down uniformly.  Making the smallest tanks the size of the A&A tanks.  As for combat values I figured people would use history to set there die roll values.  A Sherman has more armor then a Hellcat.  If the Sherman was a 3/2 die tank then a Hellcat may be a 3/1.  What sided dice or attack and defense for each tank is up to you.
When I made my first products I added jeeps and made them 1/1 and cost 3 with a move of 2.  My half-track rules were 2/2 and cost 3.  I stuck with the die 6 system because I could fit all those new pieces into that system.
