Nadaka said:Feeling shock doesn't kill you. Its the fact that shock turns certain organs to liquid (your brain, liver and lungs specifically), the typical zombie is slain by trauma to the head. HE and AP shells actually do liquify flesh in a very significant radius. A .50 cal machine gun bullet can take your arm off, even if it misses. This isn't even beginning to describe what modern weapons can do.
Felling shock most certainly can kill you, at least according to my former military medic friends. That's why it's so important to treat it. And rip a zombie's arm off? So? Doesn't feel it, no blood loss, no massive tissue trauma it cares about...you have to keep firing, and that wastes ammo. Meanwhile they just...keep...coming. AP puts holes in things, not liquefy; it's a sabot, typically. HE does concussive but little heat damage. Neither is really effective against a soft target.
You are argueing that high density concentrations of zombies will kill off the military. Civilians? In the big cities? yep, the zombies would be to dense and the civilians to poorly armed. In small towns? There are enough guns and ammo to pick off the shambling dead and render their lesser numbers moot. The military would be able to handle the large crowds in the cities with ease.
Living in one of the states with the highest density of guns to people, I can state flatly this is complete bull. Owning a gun does not equate in any way to knowing how to use it, and knowing how to use it doesn't mean you can get the vital shot. Further, people are reluctant to shoot Mom or Gramps or Li'L susie, slavering flesh-eater or not.
As for the military handling large crowds...ahh, no. They're meant to fight wars (hence the designation 'warfighter') not handle crowd control.
Could someone page the author of Year of the Zombie? His expertise is sorely needed here, and he's the closest thing to a bona fide expert as ENWorld is going to get...
