Halo: Reach Ranking Breakdown and Credit Requirements

Halo: Reach has a ranking system based on credits, the more credits you earn by playing the game, the higher your rank.  Currently, Bungie has only made ranks available up to Lt. Colonel Grade 3.  Bungie has confirmed that any credits you earn once you max your level, are still applied toward your next rank and when the remainder of the ranks are made available, you will likely skip ahead multiple ranks.  Currently, only 1% of Halo: Reach players are at the current level cap, myself included.
