(1) Where do I edit the unit numbers of specific troops?
(2) How do you modify the descr_units file so that all phalanx troops assume the distinct formation used by Macedonian royal pikemen? I've looked over the file and think I may know but not sure (royal pikemen alone are described as "greek_hypaspist").
(3) Is there any way to copy Macedonian cavalry to the Greeks as Greek heavy cavalry without having to do any reskinning?
