Act 1 - Cliffhanger

Enemy Intel Item #4

As you approach the campsite, keep trailing north until you see a radio tower. Head over to the tower and climb the ladder to the platform above. At the end of the platform lies the first Intel item of the level.

Enemy Intel Item #5

You'll find the next Intel item heading over to your fourth mission objective to meet up with MacTavish. Before following him inside the building, head over to the adjacent building to the right. Inside the building you'll see two crew workers welding an aircraft. Smash open the second window left of the door and grab the Intel item sitting on the barrel.

Enemy Intel Item #6

The last Intel item of the level is found during the snowmobile chase and will require sharp eyes. When you're about 1850 meters away, drive into the small forest area situated in the middle of the path (you'll identify when you see a small wood cabin to the right). Drive along the right path of the area and you should see the Intel item sitting on the ground (run over the Intel to add it to your collection).
