Now apply that to enemies who will not go down due to torso shots..... by the time people actually realize the only way to kill a zombie is with a headshot/blow - and... well... there might not be much military left.
Yeah, we may be trained to aim center-mass (because it's the easiest, quickest target to hit) if
we can make aimed shots, but it doesn't matter.
Purely by chance you're going to hit the head, particularly when you get to crew-served weapons like MGs simply by virtue of the amount of lead being thrown in the air (even leaving aside things like shrapnel for the moment)... seriously, it's not for fashion that we wear things called helmets.
It particularly doesn't matter since as-is pretty much everything else in the arsenal kills more people than a guy's rifle... seriously, it gets a lot of attention from the public for a weapon that only inflicts about 2% of the casualties in war. The rifle's primarily a pinning weapon, used to keep an enemy's head down so he can't concentrate on say, killing you. The real killers tend to be things like tanks, aircraft and artillery... none of which exactly require precision and none of which zombies can do squat against.
