In the meantime, career ranks are a welcome addition to the latest installment in the franchise, and as much as I enjoy playing Halo, I also enjoy being able to talk to the Halo Infinite API, so naturally my curiosity got the best of me and I started digging through the ins and outs of how career ranks are actually tracked. Players do not earn any ranked progression or ranked rewards for hitting a specific career rank (e.g., you’re not going to get the Diamond Signum for hitting Diamond career rank). Each rank within a tier has three sub-tiers, so to progress to the next level you have to complete three stages of a given rank, each with slightly more XP required than the last.
