Integrated Training Exercise, or ITX, is a training exercise on the Marine Corps Air-Ground Combat Center in Twentynine Palms that focuses on the tactical application of combined-arms maneuver warfare. ITX provides service-level assessments of battalion-size units and their associated combat support, combat service support, and aviation assets while conducting live-fire training. The purpose of ITX is to create a challenging, realistic training environment that produces combat-ready forces capable of operating as an integrated Marine Air-Ground Task Force. Marines with 1st Battalion, 5th Marine Regiment are currently training in Fire Support Coordination Exercise, a sub-event of Integrated Training Exercise 3-21.

The TRCRS site and Head Start Program, run by the MCAGCC Environmental Affairs directorate is a part of the Marine Corps’ commitment to environmental stewardship.
