The enlistment at Robins Field on 5 February 1943 might be important. Warner Robins Army Air Base was a major depot command within the Air Service Command during WW II continuing to this day by a different name. It might explain her should sleeve insignia (SSI). This Army Air Forces Medical Services in World War II document may help http://www.au.af.mil/au/awc/awcgate/afhistory/aaf_medical_services_wwii.pdf but Warner Robins is only referenced once: "In the United States, AAF medics trained at several bases. AAF enlisted medical technicians trained mostly at Warner Robins Field, Georgia, as members of the various types of small medical units authorized by the AAF."
