Bought a copy.
There is an immediate glaring error - one if it is limited to a batch or if it is in every copy.
There is a section/chapter running from page 74 to page 195 entitled
Tanks in Action, the 1930s
True it starts off in the 30s but the vast majority of the section/chapter is devoted to 1940s
Plus the book is titled Tanks of the Second World War which doesn't include much of the 30s.
Actually, just watched the video and the same error is in the review copy.
