Counterintelligence Officer
Army counterintelligence officers investigated threats such as espionage and sabotage and helped protect personnel, information, and installations. The 24 January 1972 Army manual identifies 9666 as Counterintelligence Officer, a commissioned-officer MOS distinct from warrant-officer 971A and enlisted 97B. An official Army history lists 9666 as Intelligence Research in a 31 December 1961 personnel table. These dated records establish historical usage, not a formal renaming or conversion date. No successor or effective transition dates have been verified.
