Grenz infantry
Grenz infantry or Grenzers or Granichary (from German: Grenzer "border guard" or "frontiersman"; Serbo-Croatian: graničari, krajišnici, Hungarian: granicsár, Serbian Cyrillic: граничари, крајишници, Russian Cyrillic: граничары) were combined border guard troops (include light cavalry, light horse artillery, light infantry, and line infantry) who came from the Military Frontier in the Habsburg monarchy (later the Austrian Empire and Austria-Hungary). This borderland formed a buffer zone between Christian Europe and the Ottoman Empire, and the troops were originally raised to defend their homelands against the Ottoman Turks.
