That was Oppenheimer running the show. Almost the ingenuity comes from the private sector . Richard Gatling invented the Gatling gun. The armies dating back to Roman armies all lined up and weren’t allowed to break rank, even up to the time of this invention, which the mode of thinking had to completely change. They were lined up like ducks in a row lol. I would contend it made it easy for a single shot rifle, but it shows you how trapped you can get in your thinking, especially coming top down from authorities.
