Act 1: Cliffhanger - Directly in front of you when Soap tells you to go ahead alone is a guard tower. Go up the ladder to find the Intel on the catwalk. When you are about to enter the building with Soap, go to the previous building in the alley where the Jet is inside the hanger. Break out the window to find the Intel inside. During the snowmobile sequence, when you are approximately 1,850m from the finish, stop. Look for a small wooden fence surrounding some trees in the middle of the path in front of you, and a small wooden building up a hill to the right. The Intel is on the ground inside the fenced area with trees. Just run over the Intel to pick it up.
