As a plot character, he's an isolated soldier working with limited info and his back up is usually killed. 3 games he starred in had no knife. Also, his lone wolf-ness is more due to him having anti-social tendencies due to his training and possible ptsd. And oddly enough, he's had more missions as a squad than as a lone wolf. (he was a commander of spartan squads) 2. Your biggest argument is a knife, and a poncho. I mean sure, if we're just comparing in a vacuum, destiny and the chief and ignoring the world where almost any combat unit regardless of its purpose, most likely has a knife, then yes, he's the same. But let's see, how often are deadly shoulder chargers and seismic wave ground pounds implemented I guess more people do that than use knives. Hold on, he carries multiple grenades at one time. Nope, we're both wrong chief is actually a sunsinger.
