Nice figs, man! Great use of the old firemen torsos, I often use them for 19th century Russian infantry units that fought against Napoleon. Only the Ulans' hats are a little weird. I think Imperial Guards' shakos would look waaaay better.
Yet another thing - I'm pretty sure the term "Wojsko kwarciane" (quarter army) was used for army created by Sigismund II Augustus and used in 16 - 17th century to protect Polish Ukraine from Turks and Tatars. And it consisted mostly of cavalry.
