MTI captures first place at joint warrior challenge Published May 18, 2026 By 2nd Lt. Sadie A. Largent 37th Training Wing Public Affairs JOINT BASE SAN ANTONIO-LACKLAND, Texas -- Against the very best from every branch of the military, individuals forged in excellence, discipline, and relentless commitment, an Air Force military training instructor stood tall and emerged victorious. Master Sgt. Jesus Cintron, assigned to the 320th Training Squadron at Joint Base San Antonio, Lackland, earned first place in the inaugural Joint Warrior Challenge on Fort Jackson, South Carolina, April 20. Cintron out performed four other top-tier competitors demonstrating the standards he cultivated within the MTI corps. The Joint Warrior Challenge spanned four-days, pushing competitors to their absolute limits through a gauntlet of physical, tactical, and mental tests. The competition is designed to test every facet of a warfighter’s capability, moving from grueling physical exertion to high-pressure academic and instructional evaluations. Day One kicked off with an assessment of physical and professional readiness. Competitors tackled the Army Fitness Test, consisting of deadlifts, hand-release pushups, the sprint-drag-carry, a plank, and a two-mile run, followed by a rigorous Sergeant Major’s Board. This board served as an operational and strategic exchange of training tactics, strategies, and best practices among all military branches. Day Two tested tactical and marksmanship skills, requiring individuals to conquer a Night-to-Day Land Navigation course by locating five points over 11 miles. This was immediately followed by the Fit-to-Win obstacle course, M4 zeroing, the Army Marksmanship Qualification, a written test, and a 350-word essay. This first essay required competitors to explore whether empathy and authority are interchangeable for a Military Training Instructor, how to apply empathy without losing authority, and the potential obstacles encountered when balancing the two. Day Three shifted the focus to instructional proficiency, challenging contestants with three roundtable teaching sessions consisting of 35 12-minute lessons, along with a second 350-word essay, and three written tests. The second essay examined the necessity of intensity, speed, and demand in training, the obstacles Military Training Instructors encounter regarding intensity, and the reasons why some instructors might overextend those boundaries. Finally, Day Four tested pure endurance with a 12-mile ruck march, requiring competitors to carry a minimum 35-pound dry load in addition to an Advanced Combat Helmet, Tactical Assault Panel, and their rifle. The day concluded with a two-minute ice-water dunk and calisthenics, culminating in a second Army Marksmanship Qualification Battle March and Shoot. "MSgt Cintron’s exceptional performance reflects the physical endurance, tactical skill, and mental resilience that define our MTIs," said Col. Bill Ackman, 737th Training Group Commander. “Achieving first place in a joint-service competition is a remarkable honor and brings distinction to our training mission.” As the Joint Warrior Challenge concluded, Cintron traded his ruck sack for his campaign hat and returned to his primary mission under the Texas sun. He resumed the daily, rigorous schedule of transforming civilian recruits into the Air Force’s newest Airmen. Because in Basic Military Training the mission remains unchanged: instilling the exact same discipline and precision in his trainees that secured his victory at Fort Jackson. -30-
