While playing a custom battle I noticed that the Koinnon Hellenon could choose the unit "Greek Phalanx", the kind with the long spears, like the Makedonians have. However, I have the highest level barracks built in all my Homeland provinces, but I am unable to build that unit. Is there some kind of reform or event that needs to happen to make this unit available? Or is it available in custom battles only? Thnx.
