Commendations (Halo: Reach)

Commendations in Halo: Reach are earned by performing certain feats during campaign, multiplayer, and firefight gameplay. Players earn credits as they perform these actions, many of which are Medals. Additional credits are earned upon reaching commendation milestones. For example, performing a certain number of assists in campaign, a player can earn the commendation, Support Role. Once a commendation has reached the silver state or higher, cR is only earned from reaching milestones.

Commendations are intended to also serve as an indication of how a given player tends to play Halo: Reach.

Milestones
Rewards vary with each Commendation.
 * Iron rank (1 bar)
 * Bronze rank (2 bars)
 * Silver rank (3 bars)
 * Gold rank (4 bars)
 * Onyx rank (black bars)
 * Onyx Max (black bars with fire): 0 cR

Trivia

 * When a commendation reaches Onyx MAX, the image of it on Bungie.net cannot be "dragged and dropped" as all others can. This is because the flames in the Onyx MAX image is an added layer on top of the original Onyx commendation image, not a singular graphic.
 * If players complete all of the commendations for Halo Reach, they will have earned more than 260,000 credits from the commendation bonuses alone. Note that unless the player engages in serious boosting, these will be a tiny fraction of the credits that the player will have received by then anyway (2% to 4%). Non-afk commendation farming methods are, overall, an inefficient way of getting credits.
 * Not only does credit farming boost commendation progress, but mainly intended to achieve credits for lower ranked commendations. Ex: Iron commendation allows the player to still get 12 credits off each Covenant kill, while at the same time adding that one kill to being one point. That one point goes into the Iron commendation. So you get credits for killing and achieving commendations.
 * There is possibly a reference to Bungie's beloved number 7 on the commendations. Near the commendation's symbol, there is "L43Q" seen (or possibly "L430"). 4+3=7
 * Commendations cannot be earned on the Easy difficulty setting.
