Well, to be fair, the guy across the map plinking at you is a zombie, or undead, or mutated, or whatever, and he appears to be shooting from the hip, at a great distance, usually with reckless abandon and with little to no effort put into trying to control the weapon, his chances of hitting you from that kind of distance is kind of fuck-all really.
(I liked how the books explained this, that zombies never blink, so their eyes dry out and they can't really see properly anymore)
Now, if we were to have a guy who's more aware of his surroundings, who still has some of his old mind left in his head, and isn't stiff and clumsy, say, he's just possessed by a demonic spirit, but mainly keeps his faculties in a relatively working order, I could see that totally be a much better threat.
He remembers how to aim from the shoulder, he instinctively fires in short bursts and tries to keep his weapon under control, he has in the back of his head how to use cover, he still has his blink reflex, so he can still see, he can orient by sound much better. He's not all there, but he's about as much of a fucker to fight as when he was alive, except he doesn't really fear anymore, his mind consumed with rage, voices in his head telling him what to do, strange visions flashing before his eyes, a hunger for human flesh, doesn't much remember who he is as a person, the people he used to know, the things he did, all he knows now is KILL.
A Possessed Soldier, if you will, a step up above the Former Humans, and the Imps, a threat that can't wait, something you need to resolve as soon as possible.
Kind of like the Doom 3 Z-Sec's, except much more dangerous.
