The valley is filled with smoke from the mortar attacks. You must find your squad, but the forest is swarming with Nazis. Move down the path past the burning truck and mantle over the aircraft debris.
Get your pistol ready, as a dog will emerge from the wreckage and attack. A large German patrol is just ahead, too. Attempting to take them down using just a pistol is not a good idea. You can completely avoid this fight by going through the right side of the wooded area. Go prone near the tree jutting out of the edge of the right area. Once the patrol passes, crouch and move past them into the next section.
This leads to a large area patrolled by a soldier with a Flammenwerfer. The easiest way to get through this section is with stealth. Follow these steps to make it through unnoticed.
Drop down behind the soldier with his back to you on the right.
Perform a melee attack on him. There’s another soldier patrolling the wall to the right. If he’s walking toward you, wait for him to turn back on his patrol. Sneak up behind him for a stealth kill.
Scale the wall and move toward the bunker.
One last target remains: the guard near the German bunker. Sneak up on him and perform a melee kill. Turner arrives to take out the second guard.
Fog of War
If you manage to make it through this section without being detected, you will earn this special achievement/trophy.
Objective: Follow Turner
Turner leads you through the bunker. Make sure to grab the med pack on the wall, then open the door. Search the corpses in the dried-out riverbed to rearm weapons.
