Hello, for some time I have been looking for information about the unit in which my great-grandfather served, what I know for sure is that it was a unit of the Austro-Hungarian army, and that he took part in the battles of the Italian front in 1918, on the back of one of the photos, written there is " Komp 13" and on the other one: "Haiterwank in Tirol" but it is possible that it is misspelled or I am reading something wrong, would someone be able to help me identify this branch and the area of its operations? If I posted in the wrong section, I apologize and please move it to the correct one, thank you, also i can upload more photos if needed
