yeah, like i was saying, move in via blackhawks, hmmvws, or apcs, clear out the 4 story apartment bulding, full of snipers and bodyguards(you can fit 11 snipers in a the 11 "sniper" waypoint positions of the 4flr apartment)
this is when enemy reinforcements move in, and blow up your ride outa there, and surround your building.
thus, you gotta move it to the roof, extract via chopper (human controlled).
