Should one bullet not kill to the head? Was it intended to take two if you are using a silencer? On more than one occasion today I was very close to my enemy and using an AK74 with silencer attachment shot a single bullet straight into the head of my opponent and they did not die! Blood sprayed and they screamed but they most certainly were not dead and on all occasions it appeared the towel on their heads did not stop the bullet from penetrating their skulls hence the blood!
