JROTC is designed to teach high school students the value of citizenship, leadership, service to the community, personal responsibility, and a sense of accomplishment, while instilling in them self-esteem, teamwork, and self-discipline.

Its focus is reflected in its mission statement, "To motivate young people to be better citizens." It prepares high school students for responsible leadership roles while making them aware of their rights, responsibilities, and privileges as American citizens.

The Lewis County High School Lions Battalion is active in Raider competitions, Rifle meets, Color Guard for community events  as well as ball games, and assistance in various community activities.
