The dialog is simply hillarious. I was riding the tank and fired into a covenant camp. The was a sniper tower, exploding barrels and a whole lot of grunts were flying everywere. So i cleared out the entire camp with one blast. One of the marines said "that was a whole lot of people dying at once". And he didn´t say it with a "yeah, freaking cool"-voice. It was more like a simple observation.
Or when another marine shot the corpses he said "Yeah, i know, its a waste of ammo, but i just cant help myself!".
