Hi All, I had the exact same issue. Once you have destroyed the buildings marked by red smoke, the operator cannot move any further therefore you have to destroy the other threats.
What I done was I went to the top of the cliffs, put the Forrest behind you. If you take a walk over the ledge onto the ledge below you can see to the bottom left a Tank base/ Fire base covered in camouflage netting. Call the strike on that.
Once that has been done, destroy the moving tank on the road. In this time you will be assigned to kill unit which turns up red on your display. You will then be given the next way point.
Good luck and enjoy.
