Press start when in the menu’s. Go to, I think, the icon beside the challenge icon. Go into that and go to player and campaign. This will show you what they think you’ve completed on Legendary. Happened to me. I’ve had to play about 16 missions on Legendary to get it.

You have to be ONLINE the entire time for it to count for your Armor
