Operators are the playable characters in Modern Warfare II, each with unique cosmetic appearances and backstories. While they don't offer gameplay advantages, choosing an operator you like enhances your personal connection to the game. Operators are divided into two main factions: SpecGru and KorTac, which are assigned based on the game mode and map. Unlock new operators through the Battle Pass, store bundles, or by completing specific in-game challenges.
