Dear Mr. Arnhold,
Thank you for posting your request on History Hub!
Since you already have unit records for both units, we suggest that you request access to and/or copies of the unit rosters and morning reports. Copies of most of the monthly rosters (from November 1912 - 1943 & 1947 - 1959) and morning reports (from November 1, 1912 to 1959) for Army units are in the custody of the National Archives at St. Louis (RL-SL). For access to these records, please write to the National Archives at St. Louis, ATTN: RL-SL, P.O. Box 38757, St. Louis, MO 63138-0757 or via email at email@example.com.
Please note that rosters for Army units serving in World War II from 1944 - 1946 were destroyed in accordance with Army disposition authorities.
We hope this is helpful. Best of luck with your research!
