Seeking meaning to Military Records codes/abbreviations

Dear Ms. Forest,

Thank you for posting your request on History Hub!

Some codes commonly used on Compiled Military Service Records (CMSRs) are listed on the post CITIZEN-ARCHIVIST'S GUIDE : CMSR CODES, although we did not see all of the ones you quoted listed on that guide. Please email the National Archives at Washington, DC - Textual Reference (RDT1) at archives1reference@nara.gov and attach a scan of the CMSR and they will try to figure out what the other abbreviations might mean.

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 RDT1. We apologize for this inconvenience and appreciate your understanding and patience.

We hope this is helpful. Best of luck with your research!
