transport tanks. Very true.
Just because Hitler attacked first and grabbed those areas (5% of Russia at most) - doesn't mean he got 90%.
And even if he did, the remaining 10% was enough to defeat germans - because Germany was a cra p hole unprepared for any serious war.
Area wise - he got 5%. Population wise, maybe 10%. Soviets moved industry in less than a year and German was a toast ever since.
