rome 2 polybian manipular legion tactics triplex acies

second versions, here there are no triarii, just hastatii and principes, but there are 20 centuriae and 10 manipula for both hastati and principes, as they were in a real legion. So to give you an idea of a triplex acies at work. Only difference, centuriae here have 160 men instead of 80 (i tried to change units' size but could not)
