Northern Edge 21, the premier bi-annual joint exercise of the U.S. Indo-Pacific Command, took place this year through May 3 to May 14 in locations in and around Alaska. The exercise, which involved Air Force, Army, Marines and Navy, recreated high-end realistic warfighter training to practice tactics, techniques and procedures and to improve command, control and communication relationships, improving the joint interoperability and enhancing the combat readiness in a large force employment training scenario with a focus on multi-domain operations.
