Halo 3 multiplayer ranks
From Halopedia, the Halo wiki
This page lists the ranks that are used in Halo 3's Matchmaking.
Multiplayer ranking in Halo 3 consists of two components; Skill and EXP. Skill employs a 1-50 ranking system for ranked playlists similar to the ranks included in Halo 2 multiplayer, while EXP ranks are military-style ranks designed to show a player's experience in playing Halo 3.
Skill (1-50) ranks
EXP is awarded to players who emerge victorious in multiplayer matches of Halo 3. In team games, this requires being on the winning team while in Free-For-All this requires being in the top half of the leaderboard. Wins award 1EXP, losses award 0EXP, while quitting matches will take away 1EXP. EXP ranks in of themselves consist of two components; global rank and playlist rank. Global ranks are the player's overall Halo 3 multiplayer rank, based off a combination of the player's skill and EXP level while playlist rank are per-playlist indicators of a player's experience in that mode.
The EXP ranks are military ranks awarded to players as they hit new EXP thresholds. There are thirteen ranks total, each divided into 1-4 "Grades" - with all ranks after Gunnery Sergeant having 4 grades. Each rank's fourth grade has a unique name. For global ratings, EXP ranks are divided into two classes; Enlisted and Officer. Enlisted ranks do not have any skill threshold required to achieve them, while Officer (starting with Lieutenant) require a player to have skill and the necessary EXP value to achieve; as such, the Enlisted and Officer difference does not have any practical bearing on playlist ratings.

Several achievements in Halo 3 are tied to a player unlocking a given rank. At launch, this was dependant on the player having the appropriate global rank, though as of the launch of Title Update 2 required ranks are now in the playlist ratings system; global ranks no longer apply. As such, their specific EXP and skill requirements depend on whether the circumstance in question is pre or post-Title Update.
Several armor permutations in Halo 3 are tied to a player unlocking some of the above achievements, and thus are tied to rank. Their unlock triggers are tied to the achievement unlocks and not the rank itself, though are listed here for comprehensiveness. These include the following;
