This response was meant for the double tap thread but it got locked before I could respond to why you can't neglect the head shot. I figured I'd post it here since it seems that while the show may have canceled, the same cast of characters are appearing here in this thread.
There is a reason we shoot people in the face. A shooter may not be able to quickly eliminate a threat that is wearing body armor or hopped up on adrenaline or drugs. I've seen a guy get up and run after being hit in the abdomen with a 50 caliber raufoss round. Granted his kids still collected on his Taliban SGLI policy but it goes to show you that that a shot to the center of mass doesn't always stop your opponent. Even if that round is an explosive, incendiary, half inch wide miracle bullet filled with death magic.
This is the concept behind the failure to stop drill. I've also heard it called the Mozambique drill. The face may also be the only exposed target if your adversary is firing at you from behind cover.
We haven't had to deal with a lot of body armor equipped combatants in Iraq and Afghanistan. I've run into a few but it's far from common. Israel had a very different experience in the 2006 Lebanon war however. Hezbollah fighters were very well equipped with body armor, night vision devices, and modern communications systems. You can expect that near peer competitors will field well equipped and armored soldiers. If some clown doesn't want to go down, then feel free to put two in his chest and 28 to the face.
