The Kosovo Defense Cooperation Enhancement Act extends and expands the U.S. military training program for Eastern European national security forces during multilateral exercises. Specifically, it adds Kosovo to the list of countries eligible to receive this training assistance and extends the program's authorization from December 31, 2024, to December 31, 2026. The bill affects Kosovo's military and security forces, which will now have access to U.S. training opportunities alongside other Eastern European partners. The legislation does not specify new funding amounts but rather modifies the existing authority under the 2016 National Defense Authorization Act to include the additional country and extended timeline.
