Commander Jon-B150 was a SPARTAN-III commando of the UNSC Naval Special Warfare Command, attached to Special Warfare Group Three. Jon was the commander of Phoenix Team, an elite team of Spartans who fought during the Insurrection and the Human-Covenant War.

Traits and personalityEdit

During his recruitment for the Spartan-III program, Jon formed allegiances with multiple members of both Alpha and Beta company. Jon and others would be drawing out tactical plans for training exercises, using a young Jack-A260 to relay tactical information about weak points and numbers. This made some members of the program uneasy, as they were lead to believe that Jon's moves would easily allow Jack to be captured, and made an example of, something the III program would not be allowed to do. Despite that, he was selected by Colonel Sam Cutter for the role of Commanding Officer within Phoenix Team.

Later career and DeathEdit

Shortly before the Fall of Reach, Phoenix Team was involved in an operation on Reach which involved the cooperation of an operative from the Office of Naval Intelligence. During a car pursuit, it was revealed that he was in league with the activity, and ultimately shot and killed Phoenix's Commander, Jon-B150 to escape custody. He bled out in the hands of Lauren-A094, with him firing seven shots from his M6G to take down the agent, ultimately ending in a stoppage. They both blameed themselves for the death of Jon. After which, a "strike back" op occurred where the operative was captured and interrogated.


Jack still holds Jon's words to his heart, believing that he, next to the other members of Phoenix Team was one of his true mates.
