Napoleonic Austrian Line infantry 

The Austrian Empire was centered on the Habsburg family and their Austrian (inhabited by Germans) holdings.
Therefore it is not surprising that the German infantry made the bulk of the army that was to control the patchwork
of people, countries, holdings that together made the Austrian Empire. The others were mostly Hungarians and a few
were Wallon (from Belgium, catholic part of the Lower countries that had remained Austrian).

White was the standard usual color of Austria and Napoleonic-era Austrian uniforms were about that not really different
from the previous ones.

What changed though was the use of the shako copied from the Napoleonic model (as in most other countries) between 1805
and 1806. Strangely, all infantry troops were to wear on the helmet some oak leaves or oak-leaves-looking stuff. 

The Austrian infantry was basically made up of this standard line, with the Hungarian regiments wearing blue trousers and
yeelow Hungarian knots on the trousers. All other items were identical. In addition to the 64 regiments of the line, 
Austria used some chasseurs and 16 regiments of frontier infantry : the Landwehr.

A good army, the Austrian troops were suffering from the lack of novelty among its officers who were outmaneuvered often 
by Napoleon until a marriage was to cause a short alliance between the two countries.
