There is a problem here though with assuming 1mp = 1000men when talking grand scale. It might work for individual divisions but not on large scale calculations.
This way math would give SU less than 7000manpower or 7million men over the entire course of 1936-45 in HoI2. According to wikipedia:
I know this is some part due to gamebalance but using these numbers 1 manpower would be equal to at least 4000 men.
Thus making volunteers even less likely to be represented by manpower?
I don't think anyone would force conscript foregin soldiers... Imagine 1 division of armed angry people, gathered in the SS to fight for those that invaded their nation.
Without alot of fantasy we end up with Germany arming and educating partisans that will fight against them if this was done on anything close to large scale.
How well would Belgians fight as partisans in Belarus? Besides, just because they were conscripted doesn't mean they were
angry at the Germans, even if they didn't go particularly willingly. Leon Degrelle showed that there were plenty of sympathetic right-wingers in Western Europe who could have been conscripted. The Russians were hardly on swell speaking terms with anybody in Eastern Europe, thus also producing a sympathetic (but on the whole not particularly eager) collection of people to be conscripted. This isn't black and white. They're not volunteers or angry men ready to rebel at the first opportunity. Yes, Latvians, Estonians, some Russians and many Ukrainians fought largely willingly against the Soviets. That doesn't mean they were volunteers, it just means that they didn't like the Soviets. The 15th Latvian SS division is a good example. Fought the Soviets in Latvia and then in Germany. One part ended up in Berlin and fought the Soviets. The majority marched away from the front toward the Allies and surrendered to them. It was a very clear and machiavellian application of "the enemy of my enemy is my friend."
