Spoken like someone who has never had to do it. As Parthia I had to face down a Seleucid attempt to take back Hatra. They had phalanganites greek cav peltasts and a general. Actually they had 4 unit of phalanx pikemen each with a siege weapon. In this case 1 siege tower 2 ladders and a ram. My garrison was my Parthian usual of archers eastern meat shields hillmen and some HA. The archers flamed out the siege tower and the ram and the hillmen destroyed the ladder bearing pikemen. Killed every last one with about 20 casualties between them.

Ah hillmen the Parthian generals best friend in a siege. Good on walls, fast as all hell. Can take it to chariots no problem. The only thing they can't do is pass a brothel, horny bastards .
