Effects of difficulty level


Space Marshal
I know the difficulty settings affect aggressiveness and AI, but I'm having trouble finding the threads that detail the numerical effects of the difficulty levels (I know they're around here somewhere, but I just can't locate them).

Hero and Nightmare difficulty decrease the amount of damage you do or increase the durability of enemy fighters and wingmen, right? Or is it just Nightmare?

The highest and lowest settings "cheat" - Rookie increases your damage, Nightmare increases enemy damage. Apart from those two, the difficulty seems to just scale the AI effectiveness, and appears to affect both friendly and enemy AI in the same way (ie: on Hero, everyone is smarter than on Veteran).
