Sergeant First Class Jack Kellar is the main character of the video game Black. His rank is Sergent First Class and is a Black Ops soldier for the CIA. He belongs in Bravo team. Despite being a great marksman (Depending on the player's skill) and fighter, he is somewhat rebellious, and often deliberately disobeys direct orders (Such as when he goes through the doorway after Lennox in the first level). He is never completely seen, except for parts of his face in the interrogation cutscenes.
