A Song of Ice & Fire: Unsullied Pikemen

Although considered to be in light armor by western standards, Unsullied Pikemen fight in lockstep formations according to doctrines laid down by the Old Empire of Ghis. An Unsullied phalanx with shields locked is nigh unbreakable to cavalry charge, and even more nimble foot troops would have a difficult time getting past the wall of spears. While taking this unit by surprise is difficult, a commander should beware their becoming encircled.
