As your starting point, it is best to pick the Northern landing zone, thanks to which along your path to the first team member, you will not need to walk around the buildings in the village, which may be guarded.
After the deployment, head South and towards the zone in the woods marked by the game. Take your time, because the entire area is now being patrolled by several opponents and there are more coming. You can try to walk around them, or eliminate them to decrease the risk of raising the alarm.
The first member of the Intel Team is hiding in the spot show in the above screenshots and you can use the dog to locate him (alternatively, you could also interrogate one of the enemies to narrow down the search area, but this will, unnecessarily, take you more time). Right after you reach that member, fulton her.
