Against kuzait army's they are by far most difficult to fight.
My Army consists of 75% archers all high tier.
(forest bandits are the best for range and dps if leadership is low to convert them)
Fian champions are what you want.
Imperial palentine are good also and other high tier archers.
Place on loose formation preferably on a slope facing enemy, if not possible make sure there's good line of sight. They should be fine with little to no casualties.
Usually get a small squad of elite troops to hold off infantry. Depending on your total size of army I recommend 10-20 units. Place them in shield wall and behind archers. Move forward roughly 15 metres in front when enemy infantry are 60 or so metres away.
Horses usually consists of cataphracts and Sturgian raiders. 10 cataphracts and 20 raiders are good. Split them into groups heavy Calvary and light.
Just press F6 when your shield wall makes contact and they should clean up.
Invest in archers in my opinion very low casualties in the army make up and should be able to take on army's 2 times your strength. Also if you want you can split the archers into two groups with F7 and you can have to rows of loose formation to help with horse charges.
Crossbow men seem to lack open ground combat, try not to invest in them.
