For this area to become available, get through the first wave of enemies. From the location of the declassified mission location, while facing where the logo would be, you'll want to follow the walkway in that direction. Head down the stairs, and turn right. You should see a door that has opened, as enemies spawned from this room. Go inside, follow the hall and find the COG Tag.
