Roger L. Teeter was a graduate of East Rowan High School and attended Lees-McRae College before joining the U.S. Army. While in basic training, he was selected for Special Forces Training Group, and after a year of qualifications both physically and mentally, he was awarded the coveted Green Beret.
In 1969, Roger was assigned to Vietnam with 5th Special Forces Group (ABN), where he volunteered to be augmented to a secret unit titled Military Assistance Command Vietnam Studies and Observations Group (MAC V SOG), Command and Control North (CCN), Da Nang, Republic of Vietnam.
The unit performed clandestine reconnaissance missions in the politically denied areas of Laos, Cambodia and the Demilitarized Zone (DMZ). The two countries were recognized by the 1962 Geneva Accords as neutral territories but were exploited by the North Vietnamese government.
