Just took a look at the export_descr_units file combined with the link you mentioned. Wow. That really helps. It totally answers the question and helps me with strategy. The Armoured Hoplites do have a reduced attack when they go to the swords (5 instead of 9), and the Forester Warband get a +8 to defense vs cav, -4 defense vs infantry, and a +4 to their attack vs cav. Pila are considered armour piercing. Desert axemen are not AP. Thank you so much for the link and what file to look at.
