Need help with address.
Ok.I need someone's help here.I found one of my grandfathers old letters that he wrote to my grandmother in June of 1946.I'm trying to determine more about my grandfather.Can anyone tell me anything based on the address on the letter.It reads as follows:
Sgt. Neil Harrington
Co. 1 3rd BN. 30th Inf.
APO3 c/o P.M. NY,NY
What does the RA mean?
Who?What? Where? on the Co,BN and Inf.?
I know that the letter was mailed from Witzenhausen, Germany, but what specifically can anyone tell me about the unit?
