I recently read a not-bad article on the history of tanks at HistoryAccess.com. "A Short History of Military Tanks." What I like about it is: (a) it's brief; (b) it's non-technical (very helpful for me); and (c) it connects a lot of the dots on the development of tanks. Anyway, just an FYI for you. Lessee, now I have to decide on a little face thing....hmmm....is it just me, or is anyone else confused by what activity is taking place in the fourth row, farthest to the right?
