Need Help With Strategy Info(Like Does Elevation Make A Difference)

How does different weapon type damage effect different armor type and such.
What does level/defense/defense type ect.. do for a unit and where can I find out this information.

Thanks

here is how the type of damage effects types of armor:

small medium large fortified hero
normal 150% 100% 100% 50% 100%
pierce 75% 100% 150% 35% 50%
siege 50% 100% 100% 150% 50%
spell 100% 100% 100% 100% 75%

sry its a little bit messy

Go onto battle.net and look in the strategy guide there. It gives detailed info on all of this stuff.

I was there earlier but didn't hunt hard enough to find the info thanks.
Crud it still doesn't answer some question like height advantage, back attacks etc.. which I did find else where(other forums) but it would be nice if it could be verified.

I can't remember the exact percentage, but a ranged unit will miss approx 50% of the time when attacking a unit on higher elevation.
