Ryan Herzog

Colonel Ryan Herzog was a senior commissioned officer of the UNSC Marine Corps who was employed by the Office of Naval Intelligence. Ostensibly a member of ONI Section Three, he was in reality secretly working for Section Zero under orders from Fleet Admiral Terrence Hood. He led a variety of investigations for several years along with his friend Avi. When Avi retired, he continued to remain active despite his friend's encouragement that he join him in retirement. Although Herzog had been married, it ultimately ended in divorce.
