Andras, if I had been reviewing the book for a military history 'site, I would have been rather more critical of some of the 'assumptions' made by the author. There again, if I was Polish, I rather doubt i'd be too sympathetic either to the Soviet Union.
No, the problem, was looking at the book and reviewing it for its value and utility for the modeller. In this aspect, I believe the book is WELL worth the investment. There are gaps, but as I said in the review, the problem is researching 'at source' i.e. within the Russian Archives. Some people have been FAR too dismissive of the book. At the present moment, it's the best (bar NONE) available on the T34.
Michael, if you're making one BIG book investment, personally i'd suggest this more than the Hunnicut reprint. Very simple, this is more designed for the modeller than Hunnicut ever was. On the other hand, if you're going to build more M4s than T-34s...
