I can't quite wrap my head around how the Roman's could deal with this match up from a hand to hand perspective. Greek style phalanx pikes seemed to have significant reach over the simple Roman gladius'. Aside from running in and impaling themselves on a wall of pikes, I don't see how the Roman formations could have even gotten close enough to Greek troops to cause any damage. Was there some special tactic the Roman's developed to deal with these formations?
