Thank you for a response. a few follow up questions of course.
1.) To be clear, what are "road rules" then, other than just allowing all troops to travel through dense terrain such as woods?
2.) Villages/Cities or "built up" areas block LOS and that of "shooting overhead" but now, what are the rules for individual buildings? I have always played them as blocked LOS and impenetrable to all troop types. Could you "shoot overhead" of the individual buildings?
3.) I'm starting to feel like there is three different river terrain types.....
a.) Creek=all troops can move freely over with no blocked LOS of any kind and defended to infantry
b.) River=blocked movement of all but infantry......see original post for the infantry only rule questions/suggestions. Then the River fords allowing passage to all but Machines/Artillery and chariots. Defended to infantry still?
c.) Deep River=Just your usual body of water that nothing can cross or go in like a Lake or ocean. Defended position to infantry only again?
4.) Just to be clear then, fully rounded out hill models seem to be the best as the special "defended" status, that can only be given to infantry, will be given to the highest stand during combat.
i.) Would flyers still need to attack a "defended" stand?
ii.) Does any flat area on a hill's model count as open ground, keeping in mind that a stand needs to be more than 2cm away from the slope/crest?
iii.) Is the defended status only for combat or does it come into play when being shot at?
I will agree that the entire footprint of the hill would block line of sight and count as the "Body" of the hill in the rules.
I have started on some revisions of the terrain rules to re-submit when all rules are clarified and finished

Thank you Aldhick. I am typing them up in a Microsoft word document if you want that later on so no re-typing for you.
Anyone with other terrain types or rules please feel free to make suggestions. If I never thought about it, doesn't mean it should exist
