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.

* NOTE - In parenthesis, is the number of cR required to promote to the next rank. For example, 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.

Trivia

 * The ranks Colonel and Commander have been confirmed by the armory of Lt. Colonel players. While there are several visible pieces that require Commander, the Gold Visor is the only piece that can be seen that requires the Colonel rank.
 * Upon reaching the Lt. Colonel, you can preview Emile's skull design on the EVA helmet. Upon reaching the rank of Commander(after Bungie increases the rank cap), Emile's helmet is able to be purchased at the heavy price of 120,000cR.
 * Since the items listed when reaching Lt.Colonel specify that the needed rank to purchase them is Commander, it seems Commander comes before Colonel.
