I purchased a new Tank Book called TANKS and Armored Fighting Vechicles Visual Encyclopedia .I got to say this is an excellent quick reference visual guide book. The best thing I like about it is the fact that I can actually see the comparative differences of the same Tank but the various versions in sequential order from the first through the various mods and variations. For example a Sherman is not just a Sherman.There 10 variants. 5 of the Sherman without the oddities attached and 5 further variants for various tasks, clearing mines ect ect. My Mato Tank looks more like a M4A2 than a M4A1. Point is I can see these Tanks visual together on the same page and see teh differences. The King TIGER porsche Turret and the HENSCHEL Turret I can see the differences now. Same with teh Panzers, Panthers, Tigers ect. So this will help me clear the clutter of the differences between like Tanks. Highly recommend it the book. [8D]
