melee attack. please read.

ok first i dont know if this has been sugested or not but i think since this is a real life fps that you should b e able to hit someone over the head with you'r gun.. i mean come on if you both are reloading in real life are you going to wait till you reload or they reload? no id bash them in the skull. i dont nkow about the rest of you but this would be nice. i dont mean in instent kill but like a knife hit.... or less. but either way it would be nice. tell me what ya all think.
