Cooke was an officer of the UNSC Defense Force, first serving in the UNSC Marine Corps, and later transferring to the UNSC Office of Naval Intelligence.

Earlier in his career, he would serve in the UNSC Marine Corps Biological Warfare Defense Company, but by 2553, his unique aptitude in biological warfare led to his reassignment by the UNSC Office of Naval Intelligence to Section Three's Department of Biological Warfare. In 2554, he would become personally associated with PATRIOT and SCARLET.
