The land forces of the Austro-Hungary Army consisted of the joint army (Gemeinsame Armee), national defense units and the reserve force of general mobilization (Landsturm). The army conscription encompassed men aged 19 to 50, and in the Hungarian part of the empire men aged 19 to 55. The time of service on the frontline, depending on the formation, lasted between 2 and 4 years. The official language was German, but the army naturally reflected the complicated ethnic structure of the Habsburg Monarchy: the army featured the Austrian Germans, Czechs, Poles, Ukrainians, Hungarians, Romanians, Slovaks, Croatians, Serbs, Slovenes, Italians, and numerous Jews. The basic uniform of the Imperial-Royal infantry at the beginning of the First World War consisted of the uniform jacket, simple trousers and a hat in the Hechtgrau (grey-blue) colour.
