Silahposh were infantry fitted out with a panoply similiar to that of heavy cavalry. "Silah-posh" is a Hindustani word meaning "one who is armed."
They served in small numbers as a Prince's personal bodyguard. That still didn't ensure that they were loyal or would necessarily fight well : )
They were generally armed with swords and muskets, although the ones I have are armed with hand weapons only - mostly due to the fact that finding armoured infantry firing or armed with musket was impossible!
