The Tri-Mil Competition brings together ROTC programs from across Colorado to compete in a series of military, physical, and leadership challenges designed to test teamwork, resilience, and problem-solving under pressure. From tactical events and physical fitness challenges to team-building exercises, cadets are pushed to perform at their best while representing Charlie Rock and the Buffalo Battalion with pride.

More than a competition, Tri-Mil is an opportunity to build camaraderie with fellow cadets, sharpen leadership skills, and experience the competitive spirit that defines Army ROTC. Whether you’re competing for the first time or returning for another year, Tri-Mil challenges cadets to step outside their comfort zones, work together toward a common goal, and create memories that will last long after graduation.
