Also, one rocket/grenade going off in one part of the Barrens, "Is it Tuesday already?" 6-10 rockets/grenades all going off at once in the same area, "Damnit, that's enough that we have to call in the Sprawl Guard with their military-grade light tanks, assault rifles, LMGs, and grenades with launchers of their own."
Sprawl Guard: "Wait, we actually get to go out and be soldiers rather than all the other stupid stuff we have to do all the time, all right, Nancy, my Ares Alpha, is hungry!!! TIME TO FEED THE MACHINE!!!"
