Relative to the population of the USA the standing Army is minuscule and insignificant.
A favorite observation:
Every year, the U.S. Unorganized Militia performs war games. Some 18,000,000 snipers take part in lone-wolf live-fire live-target exercises, each equipped with modern long range rifles, camouflage, mapping, transport, etc all at their own personal expense, and done with a bare minimum of governmental organization. This force is larger than any standing military on Earth, and is dispersed throughout the general population.
Year after year, Operation Deer Season is a resounding success.
