High schools across the country are highlighting their soon-to-be graduating students' intentions to join the military.

Similar to college or athletic "signing days" — in which high school students officially or ceremonially declare the place of higher education they've committed to — schools are increasingly hosting "military signing days."

At Robertsdale High School in Robertsdale, Ala., on Thursday, 28 students enlisted in the military, according to Fox affiliate WALA-TV. It was the school's first such event, where the students signed paperwork to join various branches including the Alabama National Guard, the U.S. Army, Navy and Air Force.

Four students at Becton Regional High School in East Rutherford, N.J., did the same on Wednesday, also the school's inaugural "military signing" day.

Dario Sforza, the school principal and acting superintendent, told Fox News on Thursday, "We hope this inspires leaders to have the courage to recognize and celebrate all students' skills, abilities, talents and post-secondary selections — not only the academically and athletically gifted."

Alex Hunt, a student who will join the Air Force Reserve Officer Training Corps program at the University of Alabama, told WDIV-TV he feels as though his enlistment will be "more of a betterment for me."

"I'm growing as a person," he told the news outlet. "I'm going to become a better human being by coming through this. It's going to make me grow."
