Dear Sam:
Great facts to begin with.
You can most likely obtain his discharge papers from the local Veteran's Admin (home state of your dad). If he ever had any medical care from the VA, they will have a copy of his paperwork. This is how I obtained a copy of my father's discharge papers, a few years ago. Give them a try.

You and Mr. Pierce can obtain further information too, from the gentlemen who also posted in this topic. Whenever you are logged in, simply click on the USER NAME and contact them via personal messenger. I'm sure they'd love to talk with both of you. Looks like John has the unit history, so that would be a real plus!
I love the images you posted. What a great group of guys. Looks like they were having some fun that day.
Glad to hear your youngest has formed a bond with Mr. Pierce. That is so lovely and so inspiring.
