You have to have certain Achievements unlocked. if you have the Halo Waypoint app for Xbox 360 it will tell you there.
Those items and their permutations used to unlock from a combination of achievements from Reach, Halo 3, and ODST plus a minimum Waypoint Milestone level. The Milestone system seems to have gone away but if you have the achievements, you’ve more than likely already past the Milestone requirement. And as bearclawrulez wrote you need to have the Xbox version of Waypoint and a Gold account for them to unlock in the Reach armory.
Free the achievements of the game and the others game halo
Make sure you have downloaded HALO WAYPOINT first from the Xbox live market on the waypoint it will tell you what you need to do to get them. Yes you do need to have the achievements but also the right achievement rank. To find the rank you are you need HALO WAYPOINT.
