Threadcromancer Thad strikes again!
I assembled these light cavalrymen back when I was regularly updating this thread, but only got around painting them this week. The white turbaned ones are besli, a sort of conscript, and the colorful turbaned riders are gonullu, which are volunteers. The weapons are arbitrary, gonullu can be spear-armed and besli can have bows. I will probably make another pair of these units with the weapons reversed.
I will generally run the spear armed units as gallopers and the bow/saber units as trotters. The besli will definitely be Raw, and the gonullu may be Raw or standard depending on points outlays and if multiple grades of Sipahis are present.
