Sassanian Army

[Roxofarnes]

Another lamentable fact is that we know so less about the Sassanian infantry.

IMHO there could not have been as bad as they are described. I do not think of the Paighan (levy peasant militia), but of the heavy infantry and „special forces“ as the elite Daylami.

RIGHT, RIGHT, RIGHT!!!
They were inferior to the cavalry but not as bad as most of classical authors describe. Or at least not always they were like this.
Paighan, if I am correct means "footmen" so it does not necessarily mean "peasant militia". It means generally infantry.
