I really like uniforms with the base color of green. It just looks good and practical.
Pic rel are troops from the german Principality of Anhalt-Köthen. Set in 1813 we have depictions of Volunteer Jäger, who are light infantrymen/sharpshooters, and Landwehr - a militia force meant to augment the regular standing army of a given state. In 1813/14 many german states raised such formations in order to better content with the french - especially the levee en masse and the agressive skirmishing that was pioneered by France.
