Dear Mr. Smothermon,
Thank you for posting your request on History Hub!
In October 1974, the Army Standard Installation Division Personnel System (SIDPERS) included Personnel Data Cards (PDC) that replaced Morning Reports and Zero Strength Balance Reports (ZSBR) that replaced rosters. 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. For a copy of a SIDPERS record, please complete a GSA Standard Form 180 and it mail to NARA's National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. Please include the individual's name, Social Security Number, complete organization and location, and the date the individual left the unit.
Due to the COVID-19 pandemic, the NPRC was closed from March 23 through June 23, 2020. As of June 24, the NPRC entered into Phase One of a gradual reopening process. The center is currently only servicing emergency requests associated with medical treatments, burials, homeless veterans, VA Home loan guarantees, and employment opportunities. If this is urgent, please see Emergency Requests and Deadlines. We apologize for any inconvenience.
We hope this is helpful. Best of luck with your research!
