All Field Manual locations
Search the indicated locations in the listed war story to find all the Field Manuals. There are a total of 66 Field Manuals in the five war stories. Some missions do not have a Field Manual in them. Find all collectibles to get the "Enough For A Library" achievement. Each Field Manual is saved instantly when collected. Thus, you can quit out to the main menu immediately without losing any progress. You do not have to collect them again when you die and none of them are missable. You can view how many Field Manuals you have found in each mission and how many are missing under the mission selection screen. You can also pause a mission at any time to view your collectible progress. Every mission has a Codex Entry for finding all the Field Manuals in it. The codex entries are also required for several other achievements.
