My grandfather Rev. James Elwood Gibbs, Sr. was a private in the U.S. Army. He was drafted in the Korean War February 8, 1951. I don’t have his military info such as his service #/dog tag info. He was wounded by grenade shrapnel and was a machine gunner. Returned per newspaper article February 9, 1953. I need help and resource info on how to find out what his military company division was and how to find his military medal info. Thank you
