What form of armored heavy cavalry used in ancient warfare did Grivpanvar fought?
Grivpanvar The Grivpanvar (literally: neck-guard wearer), were an elite late Parthian and Sassanian division who fought as heavy knights or Cataphract cavalry. According to Roman sources, the Grivpanvar had the ability to impale two men on the long, heavy spears that they carried. Historical evidence suggests that the heavily armoured Parthian grivpanvar were at least partially influenced by the military of the Central Asian steppes, who in turn had inherited their armoured cavalry traditions from the Massagetae and the late Achaemenid Persians.
Heavy infantry Heavy infantry refers to heavily armed and armoured infantrymen trained to mount frontal assaults and/or anchor the defensive center of a battle line. This differentiates them from medium or light infantry which are relatively mobile and lightly armoured skirmisher troops intended for screening, scouting, and other roles unsuited to the heavier soldiers.
