I just found out what this bonus (which sounds incredibly simple) actually means. Take Menelik for example, +4 CS when units fighting on hills means the enemy is the one who has to stand on hills for this to kick in. It does not matter where the Ethiopian units stand, on hills or on flat land. The same thing applies for the Highlander, +5 CS when fighting on Woods or on Hills, the enemy is the one who has to stand on Woods or Hills for this unit to gain CS. Haven't tried testing the Khevsur, but I kinda expect the same thing. Anyone finds this incredibly counterintuitive, especially in Civ5 this works in the opposite direction (the intuitive direction)? Ok, bonus finding: Those similar bonuses mean they will grant you CS on attacks if your enemies are standing on those terrains (AKA attacking into those terrains) and grant you CS on defense if you are standing on those terrains. And yes, the Khevsur obeys those rules. Anyone knows if Japanese units (Coast/Coastal tiles) and the Digger behave similarly?
