This is a book or magazine about tanks/AFVs and/or military modeling.
From the folks at Panzer magazine, here's War Machine Report, a magazine series that focuses mainly on a vehicle per issue, with shorter articles on other subjects...kind of just like Panzer magazine! War Machine Report promises to go even deeper into the machines, however, and is very technically oriented. This issue features part 2 of a story on the Normandy Invasions, with support stories on the M4 Sherman and Jagdpanther. Some color photos, but mostly b&w. All text is in Japanese.
