What month in 197o are you specifically looking for?
Sorry for delay, May 1970 USMC
Dear Mr. Rath,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series titled Command Chronologies and Related Documentation, 4/1962 - 6/1/1987 in the Records of the U.S. Marine Corps (Record Group 127) that includes 29 file units for the 2nd Battalion, 5th Marine Regiment. Most of these records are digitized and are available via the Catalog. We also located Combat Unit After Action Reports and Other Operational Records, 1968 - 1970 that includes after action reports for the 1st Marine Division. The records are not yet digitized. For information about the non-digitized 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 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 RDT2. We apologize for this inconvenience and appreciate your understanding and patience. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for this inconvenience and appreciate your understanding and patience.
You may wish to review these websites: Units > 5TH MARINE REGT > 2nd Battalion; 2nd Battalion, 5th Marines - 1st Marine Division; and Marine Corps History Division Inquiries for additional information and/or resources.
We hope this is helpful. Best of luck with your research!
