I want to be a little more specific than the previous answers. As next of kin, you can request a copy of your grandfathers DD-214. This is his discharge paperwork from the army, and it will list all medals and awards received.Decorations and Citations appear in the middle of the page.Those military records are housed at the National Personnel Records Center in St. Louis, Missouri. There was a fire at that location in 1973, which destroyed approximately 16 to 18 million records, including:80 percent loss of Army records for personnel discharged between 1 November 1912 and 1 January 1960Even if his records were burned, you will likely receive his or her DD 214 form if you identify yourself as next of kin.If he is deceased, you can order the records here:NARA | e-Vetrecs .If he is alive, you can sign him up here:https://www.va.gov//get-military...If he is still alive you can request a set of replacement medals for him at no charge.
