My grandfather served proudly in the Hungarian military before emigrating to the US in 1922. The LDS library shows microfilm of the following. Is anyone familiar with these films?
Would they be of any help in my search? What information do they contain? Is there a better source for military info? Thanks in advance for any help you can provide.
