I've got an idea for a mission that I'm sure you've probably already thought of but, I'll post it anyways "just in case...".
Please excuse my ignorance for not recalling names and/or exact particulars of this story as I don't mean to disrespect. Please excuse my spelling errors as well...
During the US attacks on Afgan., CNN did a (inbedded) reporter's story that centered around two (2) US CIA operatives who were responsible for taking in the surrender of Al-Queda soldiers at a location in the desert that resembled a fortress of some sorts. Literally, truckloads of Al-Queda soldiers were being brought in and being disarmed, and it was quite apparent to an observer that the 2 CIA ops were clearly out-numbered (even with about a dozen or so Northern Allaiance soldiers there in support).
Each Al-Queda member was taken aside individually, searched and interregated and processed. It was during this operation that the American (I'm very sorry for not remembering his name) traitor was found.
Shortly thereafter, one of the prisoners triggered a grenade he'd hidden on himself and unfortunately one of the CIA operatives was killed.
All hell broke loose and the prisoners scrambled to recover whatever weapons they could find. They ran into the fortress and took control of it. The aftermath consisted of called in airstrikes, the flooding of an underground area where about 50 prisoners took reffuge in hiding, and numerous other types of attacks that included Northern Alliance members scaling the Walls of the fortress and shooting on prisoners in the compound... etc...
If there's an accurate account of this story floating around, I thought that it would make an awesome mission for your total conversion campaign!
I'm sure I speak for the entire Ghost Recon community when I say "THANKS!" to those like you, who go out of your way in using your talents to work on and supply Mods for our enjoyment.
Good luck with it!
