This series is extremely good to anyone interested in tank warfare or, indeed, military history. It is a comprehensive, detailed, documentary some of the details of which surprised me. For example, I hadn't realised that there were more self-propelled guns and anti-tank weapons mounted on tank chassis in the Wehrmacht than there were actual tanks
The 3 volumes of "Tanks" are the best I have seen so far. Well organised with good graphics and visits with commentary to AFV museums. Whilst there is some repetition of footage this is understandable considering the ground covered by the various chapters. Good historical notes round out this series.
