In todays age of high fidelity graphics I’d like to see one of two things -or both- happen in infinite.
Emblems be visible of character models. Possibly on the chest plate up front, and the helmet in back. 2nd maybe have the teretitary colors displayed on the spartan during team games in a way that isnt intrusive (maybe just a tint or shade in small patches).
With the exception of a few armor sets it’s hard to differentiate the most of them on the battle field. Even the ones that are easy to identify like Achilles can have multiple players if not the whole team sporting them.
Enabling this will not only allow a little bit of further personalization during the game. But also make it easier for a team to identify who is killing everyone one on the battlefield. And prioritize that target if there are multiple targets. Allow someone to get a little revenge on the last person who killed them because it would enable them to more effectively hunt them down. Enable a noob to make a better decision and duck a firefight when they see the best players patch on thier back (knowing that player hasnt seen them yet). And for players with Mics being able to call out who has certain weapons that are not easily identifiable on thier back or side like the sword.
