I usually get godmode headshot and then spec the person and they can't hit anything. This makes me very sad.
i think its easier to headshot people who are crouched because of the fact that people who just generally aim for the person are more likely to get lucky as the recoil goes up and hits them in the head, smaller target and a higher percentage of that target is head
If you are crouching on italy, you will get shot in the head
