There is a myth going on about slitting somebody’s throat with a knife is a silent kill. It is anything but silent. The enemy will gurgle and thrash around until his brains run out of oxygen, creating a lot of noise in the process.
No, if you want a silent kill, you gotta put your blade at the indent at the base of your enemy’s skull (bone is thin there) and slam upward at a 45-degree angle. You’ll scramble his medulla oblongata and the motor senses are cut off immediately. Now THAT’s a silent kill.
Silenced firearms would be the best, but there are no such thing as silence firearms. Only suppressed ones that still makes noise.
Just clearing a myth. Besides how would you rather die, if you had to choose: by getting stabbed and slashed to death, or by someone who knows this method, which is a fast and painless death?
