I don't know why I am surprised to see Arma 2 players effectively role-playing in their game, but it was still a bit strange to watch this video (below). It's a bunch of footage shot by a "cameraman" as he and a reporter accompany the chaps from UKTF clan in their patrols on the game. They get ambushed, obviously, and plenty of dodgy-voice acting and life-threatening excitement ensues. Get through the first couple of minutes and it actually becomes pretty tense and exciting. Good job, those men.
Relatedly, if you an Arma 2 fancier, why not join our Arma 2 community?
Full marks for effort, especially on those dodgy news tickers!
