That is a very nice tribute to your Grandfather.
My Dad was in WW2, the Korean War, The Phillipines, and unbeknowst to us he delivered tanks to Viet Nam.
He has lots of medals. ( that his gf stole from him/me.) Two Bronze Stars, a Silver Star, all kinds of good conduct, and a few more I do not know the names of.
He did not like to talk to us about any of the wars, but he did tell us about when his ship was hit by a Kamikazi ?and he was blown off. Many of his pals didn't make it, and he helped to save others.
I'm very proud of my Dad's service record.
