TEMPLE + ARCHERY + HUNTING GROUND + Master Bowmakers( don't remember what the specialty though. it gives +20 accuracy). it is the best combination for the archers.
if you have a master bowmaker you need a siegethingy in there aswell.. the bowmaker and huntingground give accuracy bonuses even to those trebuchet thingys.. and with that bonus they are the best unit in the game i had 1 of those and some misc units against a full stack of enemies, they broke before my archers even had to fire one volley
my best army has 5 of those, and some good yari samurais.. now only their cavalry can touch me and my yaris take em out fast
