Their army comp is good because they can decimate you before you reach them but also a gamble because theyre fked if you reach them with enough men. What id do is ill have the cavalry disrupt them while your infantry rushes in with archers behind in loose formation. Important thing youd have to consider is timing, have the cavalry hit them before the infantry gets in range of their archers and make sure they attack from the sides or behind for a flanking maneuver.
Basically just use cav to disrupt their volley while your men run in.
