Query: All the tanks you could ever want (almost anyway)!

This is one of the most complete books on modern AFVs that I have ever read - also one of the best. It deals with almost all of the AFVs in service today, and although it does give some rather superflous details and leave out some others (for example, rate-of-fire for the main armament), it is just about the best low-cost option for anyone wanting a book on modern AFVs. For those who can afford to buy Jane's Armour and Artillery this may seem a little short on content, but for most of us (myself included) who can't afford it, this guide is plenty good enough. On the whole, Jane's Recognition guides are really high quality. In fact, I also bought the warship and gun recognition guides.
