I think the point adzent is trying to make is that in the Halo Universe humans have mastered space travel enough to colonize other planets and yet the military still uses 20th century weapons for soldiers. Surely humans would have created something a little more deadly, accurate and technologically superior to the AR and BR. It's been something that has annoyed me since I bought the game years ago. It just seems bungie took the lazy route in the creativity department when it came to human weapons in the game is all.
