Mechanics of assaults question?

[Mr Grumpy]

This may be a question only Glenn can answer, but i thought i would put it up for discussion on the forum.

As i understand it when a assault is launched against a hex any hexside modifiers between the defenders and the assaulting force are used, sounds ok so far. :)

Now am i correct that the actual terrain the defending hex is not taken into account, so there is no difference between defending a city hex to a clear hex against a assault, if this is correct what is the thinking behind this situation. :chin:
