The 36823334 is his Army service number. This Wikipedia article has a lot of info on this subject: https://en.wikipedia.org/wiki/Servic...ed_States_Army)
You can go to the National Archives website and use the service number to request your uncles records, order of battle etc.. In my geanealogy research I have found a lot of information on my WWII, WWI, Span-am war and Civil War ancestors. Having that service number is HUGE when researching.
I reread your post and see you already new about the service number so I'm probably telling you what you already know-- Oops!
