Dear Mr. Boggess,
Thank you for posting your request on History Hub!
Copies of most of the monthly rosters from November 1912-1943 and 1947-1959 for Army units are in the custody of the National Archives at St. Louis, MO. 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 firstname.lastname@example.org. Rosters for units serving in World War II from 1944-46 weren destroyed in accordance with Army disposition authorities.
We hope this is helpful. Best of luck with your research!
