Dear Mr. Schneider,
Thank you for posting your inquiry on History Hub!
We searched the National Archives Catalog and located the General Orders and Other Publications, 1/1967 - 11/1975 in the Records of the U.S. Army Forces Command (Record Group 555) that pertains to Accession Job NN3-338-00-200 and includes various transfer numbers such as 338-80-0239 - Publication Records Set, 1967-1975 for Ft. Sam Houston (FRC Box 1). No other details are available besides the series description in the National Archives Catalog. For access to these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result we are unable to physically check the FRC for you to see if it includes Army Reserve Command files. In addition, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this information is helpful. Best of luck with your research!
