The reason there are two DD-214s, he apparently re-enlisted in 1953. It’s merely a formality, he was discharged (on paper) for a second or two. And then a new enlistment started.
The one that counts, is the dishonorable discharge. I’m surprised they pay attention to any of that stuff any longer.
I guess it’s weird, to me at least, cuz I only got one DD214 and that was at the end of my 10 years, and I relisted twice. So to see two like that made me wonder why.
