Well another idea could be as this describes =
Instead of constructing '' - divisions of armour, -divisions of mech, -divisions of horse, -div of infantry '',
why not consider this option:
you have to have the unit on your national territory for this.
You have three types of division. Trained manpower, untrained, & reserve
(the difference between being base organisation values )
You have somthing called a weapon pool ( where you produce ten thousand rifles for IC cost, you produce tanks in perhaps the amount of 50 per selection, you make the flak guns, you make the armoured cars, the stugs, the hetzers, the hummels, the jeeps.
Heck the only thing you dont make is the supplies ( which has a slider representing ammo, hats, boots what you can imagine is already there )
Then once youve deployed your divisions to your land ( lets pretend their at boot military bases ) you select which weapons divisions will recieve each.
Different types of '' boot camp unit '' (( Trained manpower, untrained & reserve )) can cost different amounts to produce and also can only own what types of weapons are suited to them. be it tanks for normal trained troops or the simple rifle & bayonet for the untrained type of base unit.
reserve can function as regular troops also but they represent the 'DAD's army or the home guards being unfit poorly organised units of also the very young. The germans had volksturm the russians had penal companies the british had their reserve troops also.
before i finish i will give an example of what you do.
build a division as normal but because of the weapon pool that you ( or the computer controls )
what they recieve is up to either you ( or the AI )
you have a unit of reserve troops in the north of your country..... give them some rifles:
you have some crack troops down in the south give them some tiger & panther tanks?
this adds strategy to the game because you can more effectivly create poorly armed divisions ( all spades for example

) except this allows you to: where it matters..... create a unit comprised of main battle tanks with the modernest machine guns & flame throwers.
the user decides where his war material goes & the coputer could perhaps have a script or limitation of what weapons it builds so that you dont for example get an american army bording ships in washington armed completely with flame throwers & [anti]mine clearing tanks
you can see how the ( in a 1940 ) german game the player would move all the old rifles to poorer troops on the west wall ( over looking beaches )
& send all the good stuff to where its needed.
The user is limited to changing what a division is comprised of be it 1 bunch of rifles & 100 tanks or even nothing ( till he has got off his ass & remembered to produce those rifles that he forgot to build )
sorry for any spelling mistakes but i havent bothered to check this yet...
