Help moving units around a battle?

[Fitch3k]

So, I've got the rock paper scissor strategy down, and seen a bunch of guides on that, so what I'm asking about is moving your army around in good formations. My battles always break down into ugly messes. No visible line, scattered units, ect.

I need even more help with naval battles, my ships just kinda of spin around playing dumb cat and mouse the the ai's spinning ships.

Naval battles are like that.

Usually it's to be expected for melee fights to disintergrate into a big mess. You're not going to have an ordered battle line as in FoTS or Napoleon or whatever. Just work on having your defensive units (naginata, yari) hold their attackers down in place, while your offensive units (katana, no dachi, cavalry) flank them and hit them in the sides and rear.
