I'm thoroughly dismayed by this "Governor" character and his plan.
A world like this, a group of NG soldiers alive are worth far more than the piddly amount of gear in their trucks. Yeah, maybe they scored a few thousand rounds of ammo and half a dozen rifles or light machine guns. And a freaking pilot? That's worth a LOT. Same would go for farmers or ranchers or skilled machinists or carpenters. I bet those NG guys had some interesting MOS's between them. Valuable ones.
When the dead vastly outnumber the living, you don't go around killing more of the living unless you absolutely cannot come to some sort of peaceful arrangement.
The food in the back of those NG trucks won't last that community more than a week or two. Packaged stores of food around the country or the world won't do anyone any good pretty soon, due to spoilage or damage from foragers... it's time to rebuild something sensible. Time to do some large-scale gardening, greenhousing for the winters, scaling up to true farming the next year.
And every bullet spent ending the life of an unknown human with an unknown skillset, brings your community or even humanity that much closer to a full stop.
A pilot!?! He could scout the area in a 100 mile radius for salvageable tractors, disc plows, dairy farms with cattle still around them or fertilizer to collect, or whatever. And do it in a day.
Instead, the Governor got himself a backlit fishtank with another severed head. I dunno, maybe the pilot died naturally from his wounds. But I doubt it, given the way that the other NG soldiers were dispatched with no compunction.
