Emblems and Nameplates (Halo Infinite)
From Halopedia, the Halo wiki
In Halo Infinite, emblems and nameplates are small icons that represent a player's identity. Emblems can be applied to player cards, chest armor, weapons, and vehicles. Each emblem has a unique set of color palettes which can be used to adjust its color scheme. Emblems in Halo Infinite are separated into nameplate, armor, weapon, and vehicle emblems, all of which may be unlocked through the same means or individually. Nameplate also determine the appearance of a user's Spartan ID, which can be seen in the Social menu and at the introductory cinematic of each multiplayer match. These background designs are unique to the equipped emblem, and may be customized via the color palettes available for that emblem. The nameplate also determines the player emblem that appears on the scoreboard during multiplayer games.
