Infiltrate the cargo ship. Locate the package.
Intel #1: Within seconds of rappelling onto the ship, you'll head down some stairs and shoot a drunk crew member. In the dark room beside him, located on a desk next to a bunk bed, is the first intelligence item. You literally can't miss it.
Intel #2: After running down a red lit hallway and watching a teammate throw a flash bang grenade, you'll enter one of the ship's large cargo containers. Down the stairway immediately to your right and next to the corpse immediately on your left is the laptop.
