You can try contacting any type of unit associations or groups, Try social media they are good for groups if unit is known. I know the American Legion Magazine has a section or a wanted ad for people looking for different types of information on individuals or units.
Dear Ms. LoPresti,
Thank you for posting your request on History Hub!
The National Archives and Records Administration (NARA) does not provide services to locate living individuals. The records in the custody of NARA were typically transferred from other Federal agencies at least 20-30 years after they were created and used. Therefore, NARA records are not usually helpful in providing current information about individuals. Please review NARA’s Locating Veterans and Service Members web pages for some ideas.
We hope this is helpful. Best of luck with your family research!
