JROTC is a federal program where the US armed services attempt to "instill in students… the values of citizenship, service to the United States and personal responsibility and a sense of accomplishment." The organization is structured similarly to the military, with ranks and uniforms.
It is also one of the most effective recruiting tools for the US military, with between 30 to 50 percent of program graduates going on to join the armed services. An estimated 310,000 high schoolers in the US participate in the program every year.
