Game interface question

[gugarcia]

Question, when I mouse over a unit I want to attack two numbers appear on top of the enemy unit, something like "-4/-1", I understand that the first number is my melee attack modifier, but, what does the second number mean ? I read the whole manual twice and I could not find the answer, any help is appreciated. thank you.

It is the defender's modification if I understand correctly,

tm.asp?m=1555113

Hope this helps.
