I see my not so funny post got deleted. I 'll try again.
Let the gigantic, gay foreign King touch you.
I will use bewegungskrieg tactic or war of movement, that means I will use the elite units like hoplites and heroes of Sparta to strike the flanks or rear, while the low quality militia units will hit the front.
NOT how many, BUT WHERE ARE THEY?????!!!!!!!!!!!!
I'd gues hoplites will be the backbone of the army, they probably have the strongest hoplites of all factions. I'd fully exploit that. Archers behind them, heavy infantry ready to protect the flanks, and some light cavalry to move around and charge the enemy line in the back.
Good luck to anyone trying to get through a gate with spartan hoplites behind it.
