Although Machine Guns were not new in the beginning of WW1 they were still quite rare in the Austro-Hungarian army with only 2.700 pieces in the entire army.
During the war the importance of the machinegun became clear and many new machineguns were produced and deliverd to the infantry but also to cavalry units (that often became dismounted) during the war and of course the mountain troops. By the end of the war more than 40.500 machineguns would be in use!
Machine gun units could be recognized by the specific collar badge as can be seen above (not my collection) and sometimes also by the clothing in the case of cavalry units as can be seen in the photo’s furher below.
Cavalry: KuK Dragoons and Honved Hussars
The cavalry units that became dismounted during the war and most often acted as regular infantry. They also had machinegun detachments in their regiments. The collar badge was the same as can be seen with the Huszar in the photo above. But the clothing could be different, specifically the jackets had some different versions.
