Halo 4 Classified Content Problems

So I went through the campaign and now have all of the terminals, and at the end of the last one I got my five codes for the waypoint exclusive content.

I put in the code but it said it was the wrong code, and it is the same code that I got at the end of the last terminal, is anyone else getting this?

Also, I have have no idea how to get the Armour from waypoint. It says that I have to complete missions from Spartan Ops (which I have done) and then visit the news on Waypoint and look for “Section 3”, but I cannot find anything about Section 3,

Help please.

Yeah, ^ This.
