      • Military Service: U.S. NAVY, KOREA
      • Service Years: 1950, 1954
    • Right Side:

      • Birth Date: OCT. 31, 1929
      • Death Date: OCT. 27, 2018

The OCR provided has some discrepancies with the visible text on the gravestone, particularly the death year for Christa Johanna Schmidt, which is clearly 2018, not 2015. The military service years are also not clearly visible in the image.
