I shudder to think where we'd be as a country today if it weren't for the "Three Johns". Especially Browning. There are some things that he invented that I'm not sure anyone else ever would have thought up, even by now. The Johnson rifle might have won WWII, but without competition from Garand and others, would it have been as highly developed as it was? All I can say is I'm glad we don't have to know.
That said, I have to side with Ric. The M1A is a truly awesome weapon, and I think old Patton would have had some good things to say about it, too.
