Now before you shoot me I should say, in combo with artly units, I have waged an early war, cause I have my own continent, to get iron, so I land 6 galleys with 6 speamen and 6 catapalts each in a stack of doom, and trust me those artly greatly help mny chances even with the 1 attack of a speaman, I use their defense to smash there offense and artly then spearmen to smash their defense, it's a rather good combo believe it or not.
