Build training facilities in all states for citizens to be combat trained without committing to the US Military

We the people would like to be offered the ability to train for combat on weekends, or in 6 week training camps without committing to the US Military for several years. The idea would be to train people to help defend local regions incase an Invasion were to happen. Training everyday citizens to respond to an invasion would ensure the security of the United States. Give us the training we need to defend our homes and the ones we love so we can be productive incase of an invasion.
