This book is an amazing compilation of the history of tanks starting from the WW1 vehicles with a history of tank warfare in WW2 and going further until the Iraqi war. The amazing thing about this book is that it contains great illustrations and two-page comparisons between tanks in the same class from different nations. It is a great starters material for anyone who wants to know more about tank warfare in general.

So I recommend this book to anyone interested in the topic (but doesn't know much about it) and, of course, it's a fun read for anyone playing World of Tanks at the moment.

SPOILER: Some tanks get obsolete in time.
