Operation Sentinel Justice Combines Real-World Medical Support and Training to Strengthen AR-MEDCOM, MRTC Readiness

CAMP SHELBY, Miss. — U.S. Army Reserve Soldiers throughout the Pinellas Park, Florida-based Army Reserve Medical Command (AR-MEDCOM) and the San Antonio-based Medical Readiness and Training Command (MRTC) trained alongside more than 10,000 U.S.

Army Reserve Soldiers, in tandem with other branches of the U.S. military as well as British and Canadian forces, during Operation Sentinel Justice and Global Medic at Camp Shelby, Mississippi, and Camp Beauregard, Louisiana, June 6–21, 2026. Both Operation Sentinel Justice and Global Medic this year created one of the Army Reserve medical enterprise’s largest opportunities to simultaneously execute a real-world medical mission while validating medical units for future operational requirements.

The result was a unique environment where medical units not only delivered real-world medical capabilities but also trained and were evaluated under conditions designed to replicate the complexity of large-scale combat and mobilization operations.
