Hey, good to see that we've got another guy on board.
Those ideas you posted are real neat I must say, especially your suggestions about the president's speech.
To make the story better, pickup has to be denied, and if the States is at war with the country, they would surely have to move in to rescue them. We have to create some sort of restriction in the plot like maybe a brokered ceasefire deal that's preventing them from doing that.
Or perhaps this, the usual "area is too hot for pickup" kind of stuff which would allow you to go with the "at war" plot.
I read of some bulletcam script and thought of an idea. I would go along with the helo music, but why not cut the music suddenly as the chopper is targeted and everything's in slow-mo. The camera would pan to some valley and zoom in to reveal a missile site (could use the DKM SA-10 addon). The weapon fires and then we could execute the missilecam (or bulletcam) and watch as it closes on the chopper. I don't know if this is possible in OFP, but everything until the missile detonation sould be in slow-mo. After that, we'll accelerate the time and play some mood music as we watch the soldiers bail out.
We might need some voice actors for the movie.
