This is probably a question that's asked quite a bit, so I apologize in advance.
My Grandpa passed away when I was still in grade school. I know he served in the European Theater of WWII. I've been told he fought in the Battle of the Bulge. I'd love to learn more about what he did during the war, but from what I understand he never liked to talk about his experience and no one in my family seems to know much. Does anyone know how I can look up his service record?
Edit: By the way, he was from the US.
This helpful post by u/Georgy_K_Zhukov should help quite a bit. If you are not direct next of kin, (un-remarried widow or widower, son, daughter, father, mother, brother, or sister) records that are over 62 years old are considered archival and accessible to the general public, so a small fee will be required if you want to access them. Be aware that a very large percentage of discharge records from November 1, 1912 to January 1, 1960 were destroyed in a 1973 fire at the National Personnel Records Center. If your grandfather's records can be found at all, they may only be fragmentary. The Army used a variety of War Department Adjutant General's Office forms to denote enlisted men's service including the WD AGO 53, WD AGO 55, WD AGO 53-55, WD AGO 53-58, WD AGO 53-90, and the WD AGO 53-98.
