Lieutenant Colonel Radin graduated from Pennsylvania State University in 1976, where she was a member of the first class opened to women in the Army Reserve Officer Training Corps program. While at Penn State, she was accepted into the flight Indoctrination Program and was the first female in the program to solo in a fixed wing aircraft. After initial assignments in the Transportation Corps, she commanded Headquarters and Alpha Company, 724th Maintenance Battalion, at Fort Stewart, Georgia, and transferred to the Ordnance Corps.
Her next assignment was again at Fort Bragg, this time as the first Ordnance officer in the newly formed 1st Special Operations Command. She served in progressive assignments on the G4 staff -- Operations Officer, Logistics Operation Division, Chief of the Maintenance Branch; and then Assistant G-4.
After two tours in the continental United States, she was ordered to Nuremberg, Germany as the Materiel Officer and then Executive Officer for the 71st Maintenance Battalion.
A tour in the Pentagon followed, where she was assigned as a Logistics Staff Officer in Tank-Automotive Division of the Office of the Deputy Chief of Staff for Logistics, responsible for the rebuilding of the fleet of Bradleys at the National Training Center. Her next assignment was as Executive Officer to the Director of Supply and Maintenance, Deputy Chief of Staff for Logistics.
The culminating assignment in LTC Radin's distinguished career was as commander of the 227th Maintenance Battalion, Seoul, Korea from June 1994 to June 1996. When the Sampoong Department Store collapsed in 1996, soldiers of the 227th were the first on site to start cutting through the debris and begin the rescue of survivors.
