Yes that clarifies things a lot for me, thanks! The part that confuses me is on page 169 under the special rules for harming a gang, there's a little countdown clock, copied also on your trifold character sheet for the rat-pack, where it shows this:
1-harm: a few injuries, one or two serious, no fatalities.
2-harm: many injuries, several serious, a couple of fatalities.
3-harm: widespread injuries, many serious, several fatalities.
4-harm: widespread serious injuries, many fatalities.
5-harm and more: widespread fatalities, few survivors.
Then, in the example, Dremmeler's gang inflicts 2 harm on Uncle's gang (Uncle's the PC), and two of his gang members just die, just like that, "looking through crosshairs" style. Uncle also takes 2 harm, since he's leading the gang. Trying to escape, Uncle's gang takes more harm, and ends up with just a few of his gang left alive, and Uncle himself badly hurt.
In your playbook, you wrote, "When you take harm as a gang, take harm as a gang," hence my confusion. How would you suggest we interpret gang "fatalities" on the gang harm countdown with the rat pack?
