Nearly 400 medical personnel from Landstuhl Regional Medical Center and 30th Medical Brigade will participate in Operation Courageous Defense, a collective training exercise designed to showcase integrated medical operations in the European theater, March 3-6. As part of their preparations for DEFENDER-Europe 20, a theater-wide exercise with the largest deployment of U.S.-based forces to Europe in more than 25 years, Army doctors, nurses and medics will be tested on their critical skills, medical readiness, and abilities to conduct expeditionary and support operations.
