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.There are currently 50 ranks so far.

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 - Not ALL of these ranks have been confirmed, so far the rank limit is at Lt. Colonel Rank 3, but you can see the rank of Commander if you're offline with the rank of Lt. Colonel Grade 3. Anything after Lt. Colonel Grade 3 excluding Commander should be ignored as there is no proof of them until confirmed.

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, one can preview many items that cannot currently be purchased, as they require ranks beyond the current level cap.
