Military and civilian professionals selected for their experience, professionalism and commitment to youth development.

EXPERIENCE
Cadre backgrounds span the U.S. Armed Forces, public safety, healthcare, education and other service professions.
SCREENING
Staff screening includes background checks and youth-protection training before interaction with participants.
PURPOSE
Many staff began as Cadets themselves and return to invest in young people.
QUALIFICATIONS THAT MATTER
XMC’s Cadre bring 400+ combined years of military experience, including a substantial number of veterans with 20–30 years of service. Military experience is complemented by youth-protection training and the qualifications required for each assignment.
At XMC, “Drill Instructor” is an earned professional qualification, not a role assigned simply because someone has worn a uniform. Our SOP requires a successful tour training new service members in a military basic-training environment. The joint-service title includes qualified Drill Sergeants, Drill Instructors, Recruit Division Commanders and Military Training Instructors.
Cadets develop leadership under adult supervision; Cadet status or military service alone does not qualify someone to serve as an XMC Drill Instructor.

XMC VIDEO
Meet the people behind the training. Review leadership experience, staffing standards and youth-protection information alongside the videos.
Published interviews share individual perspectives; they are not a roster of every Cadre member assigned to a session.
THE STANDARD BEHIND THE STAFF
Cadre screening includes CampMinder's national, state and local background-check process and pre-camp youth-protection training. Staff bring military, Cadet-development, public-safety, medical and civilian professional experience to their assigned roles.
All Cadre complete required XMC orientation before the Training Mission. Frontline shadowing with experienced staff is a preferred preparation step. Read the Orientation & Preparation Standard ↗
The published standard for high-adventure facilitation is relevant third-party activity certification. Read individual biographies for the person's experience and qualifications rather than assuming that rank or military service alone establishes a particular technical qualification.
The 2026 published program description cited senior-leadership experience across 25+ Cadet summer training programs and a program-wide average of one staff member per seven participants. The latter is a dated overall average, not an identical guaranteed ratio for every class, venue or activity.

WELCOMING NEW CADRE
Every new Cadre member has a sponsor for the first 72 hours on post. Modeled on military sponsorship programs, the process helps new staff settle in and understand the Camp Liberty mission.
The sponsor provides a thorough tour, assists with billeting, uniform, equipment and radio issue, and introduces the new member to the Commander, Command Sergeant Major, Deputy Commander, Military Cadre, civilian staff and senior Cadet NCOs. Sponsors continue to assist as needed.
Our mission, vision and seven guiding principles explain how XMC serves young people and the standards that guide our Cadre.
