Ottoman
Delis are the Turkish version of the Balkan Stradiot lancer type.
Deli means "mad", "crazy", or "wild" in Turkish. In the Ottoman Empire, it was applied to irregular troops recruited in the Balkans, chiefly Bosnians and Albanians (but Serbs and Croats as well). Most of them were recent converts to Islam and were fanatically dedicated to wage war against Christians. They wore exaggerated and wild costumes as uniforms, which were a mixture of furs and feathers of animals of prey. Their weapons also looked terrifying with exaggerated features and accessories.
Cumans- Kipchaqs- Polovtsi- Uzes: War masks, axes and arrows.
They are sometimes stated to have been the majority remnants of the Ghuzz after the Seljuqs split off, but Arab and Persian geographers were sure that they were an off-shoot of the Kimaks to the north-east and distinguished them quite clearly from the Ghuzz. They appeared at the borders of Kievan Rus @ 1050s.
The Byzantine Skythikon were originally recruited from Pechenegs, but were increasingly supplemented by Cumans (1068?). These were later settled in Bulgaria, and played a major part in the Bulgarian revolt and their army up to 1273. They were back in the Nicean Byzatine merc roster by 1243 and up to 1292. Also availlable to the Serbs as mercenaries all the way, and briefly even for the Latins from 1239 to 1261. Further afield, they sided with the Mongols by 1213 (and the Golden Horde after 1251 where they were assimilated/ merged with the Mongols by 1380, certainly by 1400) and made up to half of the Hungarian horse archers by 1243. And the Russian principalities after 1072. And Georgia. They even made an appearance under Polish colours. And the Kwarizimian "free company" in the middle east.
