The Extreme Military Challenge! Cadre is comprised of an exceptional team of military and civilian professionals from all walks of life.   Each has been hand-picked based on proven professionalism and an unparalleled dedication to youth development.   All Cadre are required to undergo an extensive national background check as well as Youth Protection training before any interaction with our participants.  

With a combined military experience of over 400 years of service, our Cadre represents many years of honorable service in the United States Army, United States Marine Corps, United State Navy, United States Air Force and United States Coast Guard.  Many started their military career as Cadets, now opting to invest in the next generation of leaders.   Some come from strong Cadet program backgrounds, civilian careers or a solid history in law enforcement, emergency medicine, U.S. Public Health Service or other service-oriented careers.   

Our Drill Instructors are all bonafide recruit training professionals, having transitioned thousands of civilians into Soldiers, Marines, Sailors, Airmen and Coast Guardsmen.  Due to the unique joint-service environment within XMC, we use the general title "Drill Instructor," regardless of the branch of service represented.

Our program grows every year; therefore, we are always seeking out high-quality candidates to serve our Challengers. Each year Extreme Military Challenge! hires 50+ Cadre members, with many being annual returns. Many of our staff are still serving in some capacity and are subject to deployments or career changes so we are always looking to add to our team. If you have a heart for young people and would like to be considered for a position on our team, please apply here.   

Extreme Military Challenge! has some of the most exceptional staff members available.  Each has been hand-picked based on their dedication to young people, military experience and first-hand awareness of the unique nature of Cadet training.  We have a staff of 40+ officers, non-commissioned officers and civilian professionals throughout the summer.   In total, we bring more than 400 years of military experience to Extreme Military Challenge!
