Dear Mr. Stelms,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the World War II Operations Reports, 1940-1948 in the Records of the Adjutant General's Office, 1917-1985 (Record Group 407) that includes records of the 4th Infantry, the 28th Infantry, and numerous other Army units during WWII. We also located the series 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 64 files related to the 4th Infantry Division in the 1940s and 31 files related to the 28th Infantry Division in the 1940s that might be of interest to you.
