In fact the very kind of response I find USELESS is when someone quotes chapter and verse from Wikipedia or some other site, as if the info was in their head.
Why?
Because if you have half a mind to try, any link you are led to will lead to a bibliography or list of sources.
I get a lot of really good info from Wiki. Not from the articles, which are usually somewhat suspect, but from all of the listed sources. Learning is a process, not a mind dump, but you know that.
Don't be one of those people who say "I can't believe each and every one of you haven't confessed that you don't know the answer to my question".
EDIT: In fact Disastermaster set you up with all you could eat in a single evening, and more. There's models for sale. books for sale, articles to read, online links to games. kind of a pain in the *** he doesn't have all of that committed to memory, but we all get old.
But seriously, go online to the Russian Army museum. Go to the Littlefield auction- I live next door to it and I'll see you there and buy you a beer.
