Well, I wouldn't say that armor in the mod was like the armor feature in Voyager "Endgame", but it provides a little more protection once the shields have been knocked out (which only occurs once the generators are truly destroyed) - but not too much, a heavy weapon with a mount against most ships will cripple or destroy them.

As I recall, the shields and armor are both leaky.
That means, after the first hit, you will be taking some hull damage.

Without armor/SIF, even a little hull damage will kill you, so you definitely need to bulk your ship up.
