Unit size, Melee attack/defense, morale, morale shocks, missile damage. So much you can do.

There's a mod like this i saw before with a picture of a woman with several arrows on her.
I asked to it's author what it did and he said he didn't remembered what it did.
So that's what it does.
Thanks.

there is a lot of morale and endurance in the workshop

perhaps... Morale and Endurance? Also the speed of units too.
