Because of the concealed nature of his survival, B312's existence became classified and the Spartan was deployed as a black operator and assassin under the Office of Naval Intelligence. Thus, these Spartans did not participate in Operation: TORPEDO, the suicide mission that resulted in the deaths of almost all of Beta Company.

As one of the few remaining contemporary Spartan-IIIs, B312 was repurposed as a counter-terrorist operator, performing black operations. The Spartan was originally a Beta Company candidate whose performance so impressed his superiors that B312 (along with a small number of their peers, designated 'cat 2') was reassigned immediately after training before the inevitable bloodbath of Operation: TORPEDO.
