I am looking for any information on my Grandfather Al, he passed away about five or so years back.

Alfred Ivan Greenfeld
He enlisted in 1949, he went to Boot at MCRD Parris Island

He served in the First Marine Division, in Korea, 1950, I believe he fought at the Chosin Reservior.
He went on to be in the reserves for several years before being honorably discharged around1955 or 1956. He was either a Cpl. or a Sgt. he might have even gone by the nickname Gunny. (despite he was not a GySgt,).

Any information would be greatly appreciated, I also have sent in a DD214 recently, but I thought this post might be useful too.

Thanks...
