I just wanted inform others of my army composition as sparta and any greek faction. I found this army invincible and can defeat any army in campaign normal difficulty. as sparta its 16 spartan hoplites, 4 heavy cavalry. thats it. Its built for the offensive. I send my hoplites to engage the enemies infantry and cavalry, then send my heavy cavalry to take out their missiles. Then i surround the enemy with hoplite wall, so no one survivies.
