Marine Air Ground Task Force Training Command
Marine Air Ground Task Force Training Command (MAGTFTC) is where Marine Corps readiness begins. Spanning seven subordinate elements — including Marine Aviation Weapons and Tactics Squadron One in Yuma, Arizona; Marine Corps Mountain Warfare Training Center in Bridgeport, California; Expeditionary Warfare Training Group Pacific and Atlantic; and multiple commands at Marine Corps Air Ground Combat Center in Twentynine Palms, California. MAGTFTC serves as the foundation for developing the next generation of warfighters. These units collectively deliver a wide range of advanced training environments that shape Marines into confident, capable, and lethal leaders. At the core of this mission is the Service Level Training Exercise Program (SLTE-P), the Marine Corps’ premier large-scale multi-domain combined arms training effort. SLTE brings together forces from across the Fleet Marine Force to conduct full-spectrum operations in complex, realistic environments. Guided by experienced planners, instructors and evaluators, these exercises sharpen tactical decision-making, strengthen unit cohesion and prepare Marines to operate across every domain. We don’t just train Marines; we make them lethal. That commitment is reinforced through the integration of live, virtual and constructive (LVC) training. By combining real-world maneuver with simulated elements, MAGTFTC replicates the challenges of future battlefields, enabling Marines to think faster, act decisively and operate as one cohesive, combat-ready force. Whether preparing for today’s missions or tomorrow’s fight, MAGTFTC ensures every Marine is ready to lead, adapt and win — anytime, anywhere. (U.S. Marine Corps video by Sgt. Makayla Elizalde and Pfc Dominic Spence)
