Dear AP Brazington:
Thank you for posting your question on History Hub!
For more information regarding unit records prior to 1917, please contact the National Archives at Washington, DC - Textual Reference (RDT1) at firstname.lastname@example.org.
The National Archives at College Park - Textual Reference (RDT2) has custody of unit histories and supporting documents for Army units for the period 1917 through 1953. However, records for Army units active during the inter-war periods (1920-1939 and 1945-1950) are incomplete. They also have custody of the records of Army units that served in Vietnam. They have a few records after 1953 that are non-Vietnam and they consist mostly of unit organizational histories and general orders. Their contact information is email@example.com.
World War I
The following series in RG 120 and 407 can provide information about where units were located during the war:
Station cards are arranged by unit and will tell where a particular unit was stationed.
Town cards are arranged by European city or town and will tell you what units were stationed in that town.
Arranged by unit. Primarily contain station information along with occasional notes by the commanding officer.
World War II
Station lists for World War II through the early 1950s are available in the following series:
RG 407, Station Lists, 1942 - 1953 (Entry NM-3 377-A)
The lists are arranged by broad geographical location and thereunder by date. The lists are generally monthly or biweekly. Each list is arranged by type of unit and thereunder in order by unit name or number. The nearest town is listed for each unit.
Given the arrangement and volume of the lists, going through them to trace a particular unit is a labor-intensive process. Unless the researcher is able to provide a narrow time span, they need to consult the records themselves or hire an independent researcher. Additionally, if the researcher wants to know where the unit was on a specific date, you’re better off starting with unit journals or periodic reports. For additional information about Station Lists, contact the National Archives at College Park - Textual Reference (RDT2) at firstname.lastname@example.org.
