Dear Ms. Tyler,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located a series titled Unit Histories, 1943-1967 in the Records of U.S. Army Operational, Tactical, and Support Organizations (World War II and Thereafter) (Record Group 338) that includes two file units; 698th Military Police Company: General Orders and 698th Military Police Company: Historical Reports, both for 1944. We also searched the World War II Operations Reports, 1940-1948 in the Records of the Adjutant General’s Office (Record Group 407) and located a history of the 698th for 1944-1945. For access to and/or copies of these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
We hope this is helpful. Best of luck with your research!
