A few more units of cavalry done for my late russians. 3 regiments of cossacks. I still need to paint the Guard cossacks to join these guys.
I always paint my napoleonics with impecable uniforms, but when it comes to irregular/militia units, I take this as an oportunity to relax a bit, and give them a somewhat shabby look.
These guys, for instance, have a mix of regulation uniforms and some plain clothes colors. All units are dressed in the blue regulation, which started with the Don Cossacks, but later became the standard for all cossack regiments.
