Commendations

Commendations are awards that players advance through Halo: Reach, during campaign, multiplayer, and firefight gameplay. Players earn credits as they perform certain actions, many of which are Medals in and of themselves. Additional credits are earned upon reaching a commendation milestone, for example by accumulating a certain number of Assist Medals. Commendations are intended to also serve as an indication of how a given player tends to operate. Commendations cannot advanced on the Easy difficulty.

Although some have similar names and even identical icons, commendations are not to be confused with medals.

Levels

 * Iron rank (1 bar): rewards 100 - 500 cR (Average = 150 cR)


 * Bronze rank (2 bars): rewards 200 - 1250 cR (Average = 750 cR)


 * Silver rank (3 bars): rewards 400 - 2000 cR (Average = 1200 cR)


 * Gold rank (4 bars): rewards 400 - 3000 cR (Average = 2400 cR)


 * Onyx rank (black bars): rewards 400 - 3000 cR (Average = 2400 cR)


 * Max'ed Out commendations look the same as Onyx but with flames if viewed on Bungie.net there is no cR reward for maxing any commendation.
