History, Eligibility, and Identification
The Korea Defense Service Medal (KDSM) honors U.S. military personnel who have served in defense of the Republic of Korea following the Korean War. Unlike campaign medals awarded for a specific conflict, the KDSM recognizes the ongoing mission of maintaining peace and security on the Korean Peninsula.
For many veterans, it represents years of service supporting one of America’s longest continuous overseas military commitments.
