Patrouilleführer
Patrouilleführer was a military rank of the k.u.k. Austro-Hungarian Army. It might be comparable to enlisted men OR2/ Private 1st class ranks in Anglophone armed forces.
However, in German speaking armed forces it was equivalent to the Gefreiter ranks.
In the k.u.k. Austro-Hungarian Army it was used by the k.u.k. Kaiserjäger as well as the k.u.k. Feldjäger; later also in the Standschützen troops, and the k.u.k. Cavalry. It was also corresponding to Gefreiter of the k.u.k. Medical corps, as well as to Vormeister of the k.u.k. Artillery corps and to the k.u.k. Machine gun troops.
Then rank insignia was a single white celluloid-star on grass-green stand-up collar of the so-called Waffenrock on gorget patch with a grass-green background.
