Hi, I recently received a copy of this picture of my grandfather and great grandfather in uniform. I know that my grandfather fought in WWI for the Austro Hungarian army. I assumed that he was part of the infantry. Could anyone of you confirm that they are both wearing an infantry uniform. Would this picture be taken around 1914? I was also wondering if it was common for father and son to serve together? The picture was taken in Slovakia. My grandfather was born in Madacka and my great grandfather was born in Ohrada. Any help with this picture would be greatly appreciated. Thank you very much
