Captain James M. Horn was born 11 January 1945 in Stillwater, Oklahoma. He graduated in 1967 from Oklahoma State University with a Bachelor of Science Degree in Psychology. Horn joined the US Marine Corps and served from 1967-1970 as an infantry officer which included two tours in Vietnam.
Horn earned the Silver Star Medal on 20 April 1969 during a battle with North Vietnamese soldiers. He realized the North Vietnamese were preparing for a major assault on his company's defensive position. Horn adjusted his defenses, directed placement of more mines, and issued orders to his subordinate unit leaders. The enemy attacked early the next morning. When his radio operator was mortally wounded, Horn took the radio and directed mortar and artillery fire on the enemy. Disregarding his own safety, he moved across the area of heaviest enemy contact. Horn's courage, aggressive leadership and unwavering devotion to duty in the face of great personal danger resulted in the enemy being repulsed and 42 enemy soldiers killed.
Capt Horn's other medals include the Purple Heart, Vietnam Campaign Medal, Combat Action Ribbon, and Navy Commendation Medal with "V" and Gold Star. After separating from the Marine Corps, James Horn joined the FBI, serving for 25 years before retiring in 1996.
