Dear Mr. Lian,
Thank you for posting your request on History Hub!
We searched the World War II Operations Reports, 1940-1948 in the Records of the Adjutant General's Office, 1917-1981 (Record Group 407) which may include records of the 349th Infantry Regiment and the 351st Infantry Regiment. Please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org to request copies of these records.

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