SUSLAK, which stands for Special U.S. Liaison Advisor, Korea, was a covert U.S. Army unit established during the Korean War in 1950. Its primary mission was to provide intelligence support and facilitate liaison between U.S. and Republic of Korea (ROK) military forces. Operating largely behind the scenes, SUSLAK personnel assisted in coordinating operations, sharing critical intelligence, and improving communication between allied commands. The unit played a vital role in enhancing the effectiveness of combined operations throughout the conflict, setting a precedent for future U.S.-ROK military cooperation.
