not unlock special mission

Hi @KILucky You can try to things I've listed below as they can sometimes fix this problem:

- Try power cycling your equipment (full shutdown of console/PC, unplugged for ~2 minutes, restart your router).
- Some items appear in your Armory, please check it out.
- Play another full match and/or earn another player rank. Remember that you will need to wait for the next round to begin before leaving the match.
- Completing a round of Combined Arms has been known to work, give it a try.

If they don't sort out the issue then you should contact an EA Game Advisor, via one of the links below, for more assistance.
