July 8 to 11, U.S. Forces Korea hosted TACHYON ECHO (TE) 25-2, a Tri-Command Technical Effects Tabletop Exercise (TTX) with over 100 participants from United Nations Command, Combined Forces Command, and U.S. Forces Korea (USFK) Command. This latest iteration built on momentum from previous exercises and further develops the Tri-Command’s ability to integrate combined-joint, all-domain operations (CJADO) capabilities in support of regional deterrence and readiness.
