About the Halo Waypoint unlockable armor

I don’t know if this has been asked before but, after looking at the requirements on the Xbox 360 Halo Waypoint, I’m confused as to why I don’t have them. And I believe the armor is called Raider but I would have to check. Anyway if anyone can help I would greatly appreciate it.

look it up on youtube you have to enter a specific code in the classified section of waypoint

some of them require you finish some of the Spartan ops and campaign

Thanks! Although I now feel like an idiot, YouTube has everything. :confused:
