hi John,
Recruitment in the German areas was partly by voluntary enlistment and a scheme of supplementary conscription, which was for lifetime service before 1802, ten years thereafter. Recruits for Hungarian regiments were organised by the Diet of Hungary by quota. There government
Each regiment had its own zone of recruitment within the Empire. The only exception to this was the Poles of Galicia, who were deemed untrustworthy and were split up across the regiments.
Austro - hungary empire was one country at the time although it had many different modern nations and cultures. there were high ranking hungarian generals.You could do hungarian comanders and units under the Austrian list
For example the british could have a scottish commander and scottish regiments. But it is a british army.
