This is a full cap-a-pied panoply of heavy Backhterets ‘mail and plate’ armor, worn with padding underneath, and typically including overlapping layers in several areas. Heavier than ordinary Backhterets, this type of armor was popular with the heavy cavalry of the Ottomans, Mughals, and Mamelukes, by the Byzantines and also in Russia and certain parts of Eastern Europe. This was effective though fairly heavy armor, normally worn only by heavy cavalry.
There is quite a bit of variation within this class of armor. Specific types can be anything from fairly simple ‘mirror’ armor to elaborate panoplies of tightly integrated mail and plate armor similar to lamellar (as depicted here), so DR could vary from 7 to 9.
Though this type of armor could be worn by footsoldiers fighting as heavy infantry, it was normally intended for heavy cavalry such as the Ottoman Sipahi.
