Letters are bugged and I am unable to 100% Under No Flag

Hi @filthygeorge 

you are suffering from the infamous Letter bug, the way to get your unlock is described all over here in the forums. Please try the following:

For PC:

1. Go to Documents->Battlefield V->settings - Move all files out to desktop,
2. Within Origin disable the cloud save feature and start game,
3. Do the mission's you are not getting the challenge counting again -> hopefully get the reward
4. Close game and put files (see1) back.

For PS4: 

1. Export the game save files to an USB drive.
2. Delete the game save files in the console.
3. Start the game. You'll have to adjust contrast and play again the intro.
4. Now, play the War Story and complete the bugged challenge. It will show correctly achieved.
5. Close the game, and restore the game save files from the USB to the console.
6. Start the game, and you'll have your reward at the armory.

For Xbox:

1. Please move the saved file from the Xbox to a USB stick,
2. Clear local and cloud saves for BFV. (This wont remove multi player data)
3. Start the game. You'll have to adjust contrast and play again the intro.
4. Now, play the War Story and complete the bugged challenge. It will show correctly achieved.
5. lose the game, and restore the game save files from the USB to the console.
6. Start the game, and you'll have your reward at the armory. 

I hope this works for all of you!  If it does xp appreciated ;-)
