To get back to the summer of '42 we would need (I think) the following:
For Germany: IIF, 38(t), IIIJ, IIIL, IIIN, IVE, IV F/2
For Soviet Union: T-26, T-40, T-60, BT-7, KV-1A, KV-1C, KV-II, T-34(41)
That's 15 total, I skipped some of the intermediate models that were not functionally different from the ones I listed. The base models for the III, IV and T-34 are already done. Seems pretty easy, based on my total lack of experience with this! How much effort went into the CMBN Vehicle Pack?
