Dear Ms. Cadieux,
Thank you for posting your request on the History Hub!
From 1964 to 1969, the Seventh US Army was stationed in Stuttgart, Germany and in 1966 was transferred to Heidelberg, Germany.
We searched the National Archives Catalog and located 35 series in the Records of U.S. Army Operational, Tactical, and Support Organizations (World War II and Thereafter) (Record Group 338) and located 66 series in the Records of United States Army, Europe (Record Group 549) that include records of the Seventh Army during the 1960s. For more information about these records, please contact the National Archives at College Park - Textual Reference (RDT2) at firstname.lastname@example.org.
