Exercise DEFENDER-Europe 20 is the deployment of a division-size combat-credible force from the United States to Europe, the drawing of equipment and the movement of personnel and equipment across the theater to various training areas.
U.S.-based equipment will leave from ports in four states and arrive in six European countries. This will require the support of tens of thousands of service members and civilians in multiple nations.
U.S. service members will then spread out across the region to establish intermediate staging bases with multinational forces and participate in various annual exercises.
These U.S. and European exercises are regularly conducted and not part of DEFENDER-Europe 20, but rather “linked” through a shared exercise scenario, coordinated mission command, mutual sustainment and common communication environment.
DEFENDER-Europe 20 is the largest deployment of U.S.-based forces to Europe for an exercise in the more than 25 years.
