I don't know any country that fielded 10 standard infantry rifles and 10 standard LMG types all at the same time. There's usually one or two standards and maybe, just maybe, another 5-7 obselete types somehow still in service (been known to happen in the WWII timeline).

German infantry for instance, on a very basic level, only have one major change throughout the conflict, from MG34 to MG42, and this would only necessitate the change in one unit in the sub-tactical format.

However, for more complex units you have two or three rifles plus the MG change. For each rifle you need only one change, 3 different units for the same time period, and then one for each MG change (if in the same timeline), which is 6 different units total.

Now in sub-tac you'd need one change for every man carrying a rifle, anywhere from 4-12 units per period when they are in service, even if you're saving room by only needing two LMG gunner units. Now multiply this by the fact that specific equipment must be alloted down the line. Instances in the OOB where 2 units were created and one given satchel charges (for example), you'd have to create one additional unit for each soldier that would have a charge (unlikely that four satchel charges in a squad would all be carried by one person. This goes for mines, etc.

I don't think you're properly appreciating that A) each combo won't exist and that B) you need to create seperate one-man formations for different persons in the squad TO&E since you're at that level. Riflemen have different kit from automatic rifle who have different kit from Grenadiers etc. For each squad of about 12-14 guys you're likely creating 3 individual units. You'd have to to get the TO&E correct. This means every time there's a change in modeled sub-equipment (such as specialty equipment as mentioned before), you need to modified each of those three units correctly, instead of just one. I say if you went and did it these variations would pile up far faster than variations in current OOBs of infantry units.
