Dear Ms. New,
Thank you for posting your question on History Hub.
The first step to obtaining that information is to verify which unit your father was in while stationed at Stuttgart in the 1980s.
Official Military Personnel Files (OMPFs) are in the custody of NARA's National Personnel Records Center in St. Louis, MO. Please complete a GSA Standard Form 180 and mail to NARA's National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. Or you may apply online at http://www.archives.gov/veterans/military-service-records/.
For the most complete copy of a personnel file, in Section II, on the line for "Other" (Specify), write "Complete copy of every page of personnel file - not an extract." You can also request a DD-214, however that form only shows the last unit he was assigned to at the time of his discharge from the service.
In 1974, the US Army discontinued unit rosters and replaced them with the Army Standard Installation Division Personnel System (SIDPERS), which included Personnel Data Cards (PDC) that replaced Morning Reports and Zero Strength Balance Reports (ZSBR). A SIDPERS contains information on the service member during the entire period of time assigned to an organization, regardless of length of time. It also includes information about TDY, AWOL, DEF, gains, losses, promotions, reductions. SIDPERS was discontinued on November 21, 1990. It is unclear if SIDPERS are available at the unit level to show all of the assigned members. We recommend reaching out to the NPRC for more information on these reports and their uses.
You can also search online for groups of past members of units once you have your father's information. Many units and divisions have active Facebook pages and other websites where you may be able to find more information on those also stationed at Stuttgart at the same time as your father.
We hope this information is helpful.
