Here are two 16 figure battalions of the Green Croats. Kleist raised a large Corps which grew and grew throughout the SYW and which, by the end of the war, included three ten-squadron regiments of cavalry as well as infantry, jaegers and artillery. I am also trying to find out more details on the flags they were allowed to carry.
Foundry does figures to cover the entire Kleist range although I don't know why they don't have a skirmishing figure. I don't think the sculptor was Copplestone but I'm unsure who designed the range.
