...the CIA HVT Ia person doesnt work fine and i was get difficulty for he follow me.

Beautiful rescue mission and nice idea and ambient and history but too many enemies within building and too many protect because we have only sight for low range combat and it do that we get too many difficulty for clear OA before assault. You could configure ammo with rifle sight for medium range combat. On SP mode this mission was for me hard and i was dead 30 time and more with save progress !
