Noi Industries is the top weapons development firm in the United States and one of the top five in the world. The title is impressive due to the company's preference to avoid focusing too much on lethal weaponry, instead making leaps and bounds in non-lethal and battle accessories. The company was founded by Duke Noi, who redesigned it from Park Tech Weapons. The company's major headquarters are in Texas in the United States as well as just outside of Seoul in South Korea. NI's annual income as of 2009 is roughly 9 billion USD.
