Wow, everyone beat me to it. I just found out and one of my first thoughts was , "Well, guess I better play the red storm rising campaign in Nato fighters..." But RIP. I don't know anything about the man, but I have certainly enjoyed a lot of Clancy-related material. It took me a couple tries to get into RSR (I mean...the war doesn't even start for almost 150 pages!)...but once I finished it, I absolutely loved it and it now gets at least an annual read through. Clear and Present Danger, Hunt for Red October, Rainbow Six...all great books.
And then of course the original Ghost Recon game (plus expansions). That is one of the few games that has never been removed from my hard drive (along with Strike Fighters and Mount & Blade).
...anyways, It's good to see a lot of folks with the same thoughts. See you in the skies over Europe!
