Ok I have looked around as much as I can and I only see that it needs to be completed by winning a PVP match thru your in game queue. I have been involved in several cap and hold wins and it still will not update. What am I doing wrong guys.
There are two missions, one wants you to play objective based maps, the other wants you to play the deathmatch style maps. So if doing salvage maps isn't giving credit then try maps like cracked planet or the ground maps.
