OK some common ground..Since Budapest is in Hungary i'll assume we agree.
The germans build roughly 25k tanks, so tiger comprized roughly 5.1%
This one i'm a little shaky on, but i believe the Russian had around 25 to 35K tanks around Jan/45. So if the Russian build roughly 1600 SU-100 During the war period that averages out to 320 a month. That's roughly 1.1%..........I'm not sure of the montly production rate of them, so i took the liberty of assuming. Yes a know what happen when one assume !!!!
Walkure
BTW i wish you would have asked me to figure out this tomorrow. I have 5 martinis in me and this is harder than you know
