U.S. Army Europe and Africa

June 5, 2025 | 4:02

Service members of the Maine National Guard, Vermont National Guard, Army of the Republic of North Macedonia, and Armed Forces of Montenegro work together with civilian cyber experts as a combined cyber defense team to identify and prevent simulated cyber attacks during Immediate Response 25 in Golubovci Airbase and Podgorica, Montenegro, May 26-June 6, 2025. This cyber exercise, the largest in Montenegro’s history, facilitates an exchange of expertise in cyber resiliency while strengthening regional military cooperation. Demonstrating global deterrence and the U.S. Army’s ability to rapidly deploy U.S.-based combat power in Europe and the Arctic region alongside Allies and partners, DEFENDER 25 brings U.S. troops together with forces from 29 Allied and partner nations to build readiness through large-scale combat training from May 11-June 24, 2025. DEFENDER 25 increases the lethality of the NATO alliance through large-scale tactical training maneuvers and long-range fires, builds unit readiness in a complex joint, multinational environment and leverages host nation capabilities to increase the U.S. Army’s operational reach. During three large-scale combat training exercises—Swift Response, Immediate Response, and Saber Guardian—Ally and partner forces integrate and expand multi-domain operations capability, demonstrating combined command and control structures and readiness to respond to crisis and conflict.
