Over 15 million Americans hunt each year. That's 15 million honest Americans who know how to stalk prey, how to kill, and who don't require firearms training. When you add that to the estimated 1.9 million active duty and reserve military personnel, you have a fighting capable force of roughly 17 million. Compare that to China with it's 2.5 million member active and reserve military force and almost zero civilian gun ownership. Now you know why NOBODY wants to invade the United States. This is also why civilian ownership of AR15s is so important.
