These are low-tier light cavalry, but their speed makes them perfect for harassing the flanks of the enemy line.
The Sogdians were an Iranian people that lived north of modern-day Afghanistan. Their land is known for its fertility, as well as its powerful archers. Sogdia's geography allowed for more manoeuvrable warfare than their more sedentary Bactrian cousins to the south. Caught between the commonly urbanised Bactrians, and the vicious nomads of the north, the Sogdians were forced to develop a fighting style that could compete with both fast horse archery and static battle lines. As such the Sogdian warriors are fierce soldiers capable of multiple styles of battle.
