Operation Rhino H- 00:40 OBJ IRON

[Deep_Thought38]

Can anyone help me with this mission please? I seem to have completed all objectives; (i.e. both towers destroyed, radar lazed and bombed, no alarms sounded, even destroyed air-traffic control centre) but the mission does not end. I've tried killing as many enemies without triggering the alarm, even those underground, and while mission brief says to go to extraction point there is no such location shown. How do I get out of here?????? Tried running all over map....no airlift shows up.

Any suggestions gratefully received.
