Mansabdaris were cavalry of officer rank generally armed with sword, lance, shield, mace and bow. Armour was of the finest quality, denoting their rank. Mansab means "rank" so Mansabdar essentially means "rank holder."
Their mounts were, generally, of excellent quality. The horse armour could be mail but more often quilted or cloth barding.
Numbers of these officers could be organised into bodyguard units, which is what I use this unit for.
