We got the weapons off some dead army guys. National Guard, whatever.
It was a weird scene: there were normal zombie remains, there were dead soldiers who had clearly been partially eaten, and there were soldiers who had been bitten and then shot.
And then, there were the corpses of soldiers that had just been shot, no bite wounds that we could see. Most of the bodies we found in the area fell into that category.
The officers must have started shooting the wounded, and some of their men turned on them. It was probably one hell of a firefight.
