this proves absolutely nothing. of course you can get a kill at long range if you fire incredibly slowly! now do the same thing at 25% that range against a moving target who is returning fire with a battle rifle. Not to mention it took about 16 hits to kill the guy in 8-10 shots...? this really is a pointless video. And you are mistaken if you think halo should be have precision starting weapons only. This far in the future damn near EVERYTHING would be automatic and have gyroscopic stabilization and recoil absorption, allowing for sustained fire on distant targets with automatic assault weapons. Im not saying halo should go this direction, far from it, but those are the facts. Things like BRs and DMRs wouldnt exist at all. Not to mention that all human weapons would probably be energy based.
