Mission 8: Ratte Factory
War Diaries: 5
War Diary 1: When you are making your way through the factory on the east side, follow the bottom floor forward and you will come to a large table that has this note sitting on it in the wide open.
War Diary 2: Once you have destroyed the first transformer, run across the bridge to the far side and then make a short right turn to look behind this metal wall. The note will be on the table directly behind it.
War Diary 5: For the last diary climb the stairs to the upper level of the tank, and when you reach it make a quick left to find the note laying on the ground there.
