A little suggestion about Prussian generals:
My first suggestion is to change portraits for Karl Wilhelm Ferdinand von Braunschweig-Wolfenbüttel and Friedrich Adolf von Kalckreuth.
Here is Ferdinand von Braunschweig-Wolfenbüttel in Prussian uniform:
And here is Friedrich Adolf von Kalckreuth in more 18th century style:
Also I suggest to replace von Gneisenau as he didn´t reached the rank of general in 18th century. He was only colonel in 1806, so I think he is more suited for Napoleonic period, not revolutionary period. The better candidate for IS late campaign is Frederick Ludwig von Hohenlohe-Ingelfingen. He was promoted to major general around 1785/1786, in 1781 he was governor of Berlin, in 1794 he commanded on Rhine and in 1806 he was promoted to Genral of Infantry and he was one of Prussian corps commander.
Aslo I´m researching twi Italian and one German faction. Progress is slower that I wish, but I hope I will be able post some results soon and it will be helpful for team.
