Hey, Nice forums... I've been trying to remember the name of a mission I loved when I used to play Ghost Recon all the time. I always played it on my lan with my buddies, good times.
Anyhow you started out at the lower end of a map, moving up you passed some grassy areas, a creek, and then up a desert hill where there was a farmhouse with several enemies. Past that there were a couple stopped vehicles with more enemies, to the left and up a hill you would eventually reach a bridge I think...with a large canyon. But if you continued up the hill ignoring that part eventually you would trigger 2 or 3 tanks out of the canyon which you would have to disable.
It was definitely a desert sniper map, I hope someone remembers the name of this because it's driving me insane.
Thanks!
