Dear Mr. Denney,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Photographs of American Military Activities, ca. 1918 - ca. 1981 in the Records of the Office of the Chief Signal Officer (Record Group 111) that may include the photographs you seek. For access to these photographs, please contact the National Archives at College Park - Still Picture (RDSS) via email at firstname.lastname@example.org and their web site is httpsg://www.archives.gov/dc-metro/college-park/photographs-dc.html.
Group photographs taken at basic training or boot camp were not considered permanent records unless the photographs were taken by official military photographers usually for publicity. Photographs of various U.S. Army, Navy or Marine Corps activities from 1940 to 2007 (that are permanent) are in the custody of the National Archives at College Park - Still Pictures (RDSS). Please contact RDSS via email at email@example.com.
Usually, the instructor of a training facility paid a civilian photographer to come to the base to take pictures. These photographs sometimes are filed in the records of the unit but oftentimes they are just distributed to the individual members with no permanent copy kept.
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 of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from National Archives at College Park - Still Pictures (RDSS). We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
