Leon might be on to something here and in light of that, I'll be more straight forward. It would be in the best interest of the rescue team to have the snipers on the roofs provide cover fire while they advance toward the chopper, if resistance doesn't mount to quickly, getting to the chopper will be easy enough, getting back will be a bit of a fight, but it shouldn't be too hard with snipers keeping the enemy pinned.

Also, I'm pleased with old man Stan's outcome as well, thanks again, HWWB.
