Btw, can somebody shed some light on the nature of Greek mercenaries? They always seem to be equated to peltasts, but on at least one source I've read about Ipicrathes equiping them with longer then usual spears (but not full length pikes) that were so long they had to be weilded dual handed, and they were equiped with a shield smaller then the hoplon strapped to the arm.
Did this type of "imitation hoplite" really exist, and were they widely used
