Thank you Dark horse spirit!...lol I know that is not a sarissa I wrote the question in a wrong way sorry.The question was-Units that carry sarissa or xyston are both hoplites?-now I have a answer-yes.Yes but difference is in hight-sarissa(from 5 to 7 meters).For example royal pikeman use the sarissa,but hoplites(most of them from greek cities)use the shorter one called dory(Sorry for the wrong information above!).Armoured hoplites(greek cities) carry xystons(about 3,5 to 4 meters)...
The hight is right dont change it for the spartans!
