Rank (Halo: Reach)

The Ranking System in Halo: Reach is based on Credits (cR) earned through Forge, Multiplayer, Campaign, and Firefight matches. Credits are earned after every game, and you earn extra credits for medals earned during the match, (e.g. Double Kills) victory bonuses, commendations, and Daily/Weekly challenges.

Note that Credits spent on armory purchases do not decrease your rank. However, Credits (cR) earned from any other feature (Forge and Custom Games) are likely to be a lot less than those that would be awarded for playing multiplayer via Xbox Live. All ranking is currently capped at Lt. Colonel Rank 3 at this time.

* In parenthesis is the number of Credits required to promote to the next rank,e.g. to advance from Captain Grade 3 to Major requires a gain of 46,000 cR. There is no minimum amount of cR required for any rank.

New ranks past Lt. Colonel Grade 3 are set to be available soon. Bungie stated in the weekly update of 09/24/10 "We’ll absolutely be raising that Cap (for Free) in due time. When the level cap is lifted, new ranks become available and there’s yet more Armor to unlock. But how and when are we going to lift the cap? More appropriately, what are you going to do to lift it ?  There'll be another time. "

From this information we can only assume that the new ranks will be released when the community hits a certain amount of kills or games and will possibly include something to do with the final Mission "Lone Wolf".

The rank "Inheritor" can be seen as "MAX RANK" in many screenshots and videos released by hackers and modders. Some speculation throughout forums believe this rank is Bungie only.

The ranks Colonel and Commander have been confirmed by the armory of Lt. Colonels. While there are several visible pieces that require Commander, the Gold Visor is the only piece that can be seen that requires Colonel.
