The thing about zombies is, well, they're zombies. They'll only stop standing around in nice runoverable groups when there aren't enough of them left to. They're not capable of adapting to enemy tactics because they're dead.

That's another element that makes any military vs. zombies story not work except as a crushing defeat of zombies, because they're literally 100% predictable in all situations.
