I'm planning on making my own custom armor for my Halo project. And that got me thinking, why haven't we seen any models of armor or weapon designs come from the soldiers of the Army of the UNSC or Colonial forces? In our world some of the most effective weapons were designed by soldiers themselves. The Mosin Nagant designed by two men, one being Captain Sergei Mosin. The AK-47 was designed by infantryman Mikhail Kalashnikov. The M16 by Eugene Stoner. Etc. So why have we seen nothing of this sort in the Halo universe, especially after 540 years from our own time. One could say that it's difficult enough to arm a solar system spanning civilization network with technology developed by the more advanced entities like the UEG and ONI. However that doesn't mean that a design concept developed by a non governmental individual wouldn't be considered if it showed potential and was efficient in it's operation. I'd be thinking that such experimentation in firearms and armor designs would be more likely on the Colonies, either those with vast resources or the Outer Colonies, where the threat of outside forces and the hardships they live by would breed a mentality of ingenuity and endurance. I'd like your folks' takes on this topic.
