LOL, yes we did just that!!
My main thought here was the 76mm Sherman compared to the 75mm Sherman, that to me a a difference here, as I did'nt know the numbers before. Yes, a combined effort here is the key, say you take away the trucks, and put Sheramn 75mm tanks in their place, plenty of tanks, but the supplies to keep em' going........??
It did seem lile some of the Russian tanker crews liked their comfortable Shermans, but many thought they were also under gunned and under armoured, then there is the narrow track issue and terrain turning and throwing tracks I think as well.
Cheers, to me it comes down to it was better than nothing at all, in many respects.
