To a foreigner, the United States’ military might is a defining national characteristic. But how does that express itself in everyday American life?

That’s what Dutch photographer Ellen Kok sought to investigate when she spotted a group of uniformed teenagers — cadets in a Junior Reserve Officer Training Corps (JROTC) program at Fall Mountain Regional High School in Langdon, N.H. — at a parade in 2010. She ended up spending more than two years with the group, documenting their routines, rituals and training regimens.

There are 314,000 cadets in more than 1,700 JROTC programs across the country. Many of those cadets, including some of the young men and women Kok captures in her book “Cadets” (Netherlight, 2013), go on to serve in the armed forces, but a better sense of citizenship — not recruitment — is the goal of the program.

Though they can cut quite imposing figures in their uniforms, ultimately, Kok’s cadets are not simply made out to be miniature warriors. Rather, her frequently unguarded, often humorous photographs are primarily a look at the lives of teenagers — prone to the same joys and growing pains as young people anywhere else in the world.

“‘Cadets’ is not only about kids in uniform or the influence of the military. It is also about American small-town daily life, traditions, culture, relationships, the importance of family, community and team work,” Kok said via e-mail.

Cadets have to mark their initials in their dress shoes so they know which are whose. Another cadet had already used the initials JB, so Maj. Cenney came up with an alternative and made these drawings in cadet Josh Baker’s shoes. (Ellen Kok)
