That is from a "TEASER" trailer, which means it isn't from in-game footage. Every other clip they made IS. ..and no, that isn't mastchur, it's made up, just like the intro video for battlefield veitnam and 1942, except.. not as good. lol
Mmh yeah there were some things released before the game was out, that aren't in the game ... For example when u look on the backcover, you see a blackhawk with missles (or gas tanks) you can't find this in the game ... that sucks ... oh well I guess the BH would kick even the jetpilot's asses
