Dear Ms. Viloria,
Thank you for posting your request on History Hub!
We searched the Access to Archival Databases (AAD) and located the World War II Army Enlistment Records database and located one file for "Viloria, Urban[o] B" (DOB 1907) that may be of interest to you.
If you have not done so already, we suggest that you request a copy of your grandfather’s Official Military Personnel File (OMPF). OMPFs and individual medical reports for enlisted men of the U.S. Army who were separated from the service after October 1912 and before 1959 are in the custody of NARA's National Personnel Records Center in St. Louis. In many cases where personnel records were destroyed in the 1973 fire, proof of service can be provided from other records such as morning reports, payrolls, and military orders, and a certificate of military service will be issued. Please complete a GSA Standard Form 180 and mail it to NARA's National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
Please note that the "official" photograph of an individual is not considered to be permanent federal records by the respective military services and is not retained in a separate collection by the service. If the photograph you are seeking still exists, it will most likely be found in the individual's Official Military Personnel File (OMPF). However, there is no guarantee the photograph will be present.
We searched the National Archives Catalog and located the series Guerrilla Unit Recognition Files, 1941-1948 in the Records of the Adjutant General’s Office (Record Group 407) that includes one file that contains a reference to "Viloria, Urbano" and two files that contain reference to the "2nd Filipino Bn" (Battalion). These records have been digitized and can be viewed online via the Catalog. Plus, we located the World War II Operations Reports, 1940-1948 in the Records of the Adjutant General's Office, 1917-1985 (Record Group 407) that may include records of the 1st & 2nd Filipino Infantry Regiments and 2nd Filipino Infantry Battalion during WWII. Please contact the National Archives at College Park - Textual Reference (RDT2) at email@example.com with any questions you might have about these records.
We also located the series Project Decimal Correspondence Files, 1942-1947 in the Records of Headquarters Army Ground Forces (Record Group g337) that contains the file "Pacific Theater of Operations, 1942-43: PTO 220.3/1 List of EM of 1st & 2d Filipino Regts". These records have not been digitized. For access to and information about them, please contact RDT2.
In addition, we located the series Military Files, 1942-1945 in the Map Room Papers (Roosevelt Administration) (Collection FDR-FDRMRP) that includes the file MR 203(2) Sec. 10 War Department Operational Summaries - October 1942, which notes the establishment of the 2d Filipino Regiment. These records have been digitized and can be viewed online in the Catalog. Please contact Franklin D. Roosevelt Library (LP-FDR) at firstname.lastname@example.org for assistance with these records.
Next, we located the series Army - Navy Screen Magazine, 1943 - 1958 in the Records of the Office of the Chief Signal Officer (Record Group 111) that includes the file ARMY-NAVY SCREEN MAGAZINE, NO. 13, which shows Filipino infantry regiments training and relaxing and shows the 2nd Regiment receiving bolo knives. These records have not been digitized. Please contact the National Archives at College Park - Motion Pictures (RDSM) at email@example.com for access to and information about these records.
Plus, photographs of various U.S. Army activities dating from 1940 to 2007 are in the custody of the National Archives at College Park - Still Picture (RDSS). Please contact RDSS via email at firstname.lastname@example.org or review their website at Photographs and Graphic Works in College Park, Maryland.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2, LP-FDR, RDSM, and RDSS. Also, the NPRC is closed except for emergencies. Currently, NPRC will continue servicing requests ONLY associated with medical treatments, burials, and homeless veterans seeking admittance to a homeless shelter. If your request is urgent, please see Emergency Requests and Deadlines. Please refrain from submitting non-emergency requests such as replacement medals, administrative corrections, or records research until NPRC returns to pre-COVID staffing levels. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for any inconvenience.
Finally, the US Army Center of Military History has some information on their website about the History of the US Army's 1st Filipino Regiment and 2d Filipino Battalion (Separate) and about the 2d Filipino Regiment that might be of interest to you.
We hope this is helpful. Best of luck with your family research!
