Part 18

After completing the "defend Alpini outpost" objective, head to the objective on your left. Enter the large tunnel entrance, go downstairs, turn right, and find the collectible crate on the right side just past a couple of soldiers. This is Field Manual #33.

To find Field Manual #34, reach the first part of the fort, stay outside, and skirt around the north and west sides. Follow the path south-west then south-east until you reach a bunker entrance visible on your minimap (a display showing your surroundings and nearby objectives) at the southern corner of the map. The crate is behind the partial dividing wall in the middle of the downstairs room.

Exit the bunker and head right along the path to the blue-framed door that takes you inside the fort's perimeter wall. You will be forced to complete the "clear the Austrian horn" objective. Rush into the courtyard, drop down into the sunken area in the centre, and enter the tunnel to the east side. Follow the passage into a large vaulted room with several bunk-beds. Field Manual #35 is between the first and second beds in the northern corner. It is recommended to grab this during the firefight as going out of bounds to get it will cause you to die and respawn (be brought back to life at a checkpoint after death) at the start of the objective.

Field Manual #36 can be obtained during or after the firefight but before the final objective. Go behind the building on the east side (flank around outside at the south-east corner or pass through the north-east room). The crate is next to the building wall at the north end of the fenced area. Remember to get all five collectibles before going to the big blue doors at the end of the mission.

The Codex Entry - Alpine War is unlocked for finding all five field manuals in this chapter.

The location for War Story 4: The Runner is the Dardanelles at Gallipoli in Turkey.

The Codex Entry - The Dardanelles is unlocked by completing all chapters in this story.

Trophy #16 - The Runner is earned by completing all chapters in this story.

Trophy #21 - The Hills of Gallipoli is earned by unlocking all the codex entries in this story.

After completing all codex challenges and finding all field manuals in The Runner story, you will unlock a Howdah Pistol skin (Frontiersman) for multiplayer.

In War Story 4: The Runner - Chapter 1: Cape Helles, storm the beach and clear enemy positions. Ensure you have all five field manuals before capturing Helles Overlook ("A" objective).

The Codex Entry - The Big Guns is an unmissable unlock for completing an early mandatory event.

To unlock the Codex Entry - Torpedo Exploit, you must get ten headshot (a shot that lands on the enemy's head, usually an instant kill) kills (a kill to the enemy's head) during the chapter. Your starting primary weapon, a bolt-action SMLE carbine, can reliably achieve a one-hit headshot kill. Aiming is limited at range by its early reticle sight. It is possible to get sniper headshot kills on enemies like MG operators, but spotting your target first makes their outline clearer. Peeking cover (press the cover button to crouch behind walls or objects) on Hard difficulty offers little time to aim before taking damage, requiring you to return to cover to heal. Use angles with fewer enemies and know that your headshot kill count does not reset upon respawn (when you reappear after dying). You can replay an Easy mission to obtain this codex entry if necessary.

Field Manual #37 is found by following the first level of trenches south from the beach, taking the lower left path at a fork, and continuing until you reach the machinegun nest at the far end. The crate is next to the machinegun position, in a wooden shack with a field gun inside, on the east side between the shack and the outer sandbag wall next to the beach.

Field Manual #38 is located on the beach. Backtrack along the first trench until you reach two weapon crates. Stand between them, hop over the wall onto the bench, look left, and you will see three boxes, one of which contains the field manual.

Field Manual #39 is found by returning to the weapon crates in the lower level of trenches and taking the right fork uphill south-west, west, north-west, and north into the next level of trenches parallel to the beach. Follow the trench north to the end, which is blocked by rubble. Look to your right; the crate is in the open area.
