Let's talk about cavalry

[Titus Marcellus Scato]

That would be one of the many reasons I stay well away from the steppes or far east. As someone who's primarily an infantry general, horse-archers aren't something I want to deal with.

Yes, HA are bad news. Two strategies (for infantry) work against them - hiding behind stone walls (Greek tactic), or swamping them with vast hordes of cheap arrow fodder so the HAs run out of of arrows and then get owned in melee in the corner of the map (Persian tactic). Although your losses will be far worse than theirs.

I'm planning a third approach in my Epeiros-as-Bosphorous Kingdom game, a combined arms tactic that's different from those two. Have your own horse archers, plus an infantry force (including foot archers) who are well-armoured enough to make their arrow fire ineffective. Allegedly ten points of armour is usually enough to preserve an infantryman against arrows. Close to that plus a shield from the front.

Basically the heavier infantry protect your archers, who harass the horse archers from range, while your own join in the shooting. When they run out of ammo (and are hopefully whittled down some), your horse archers and medium cavalry chase them down.
