209th Detachment, 2325th Group (Korean: 2325부대 209파견대), commonly known as Unit 684 (684부대),[1] was a black operations unit of the Republic of Korea Air Force formed to assassinate North Korean leader Kim Il Sung in 1968,[2] in retaliation for the North's botched Blue House raid. The unit consisted of 31 civilian recruits, mostly petty criminals and unemployed youths, and underwent three years of harsh training on the island of Silmido. The assassination mission was cancelled in 1971 and the unit mutinied, resulting in a firefight in Seoul in which most of the members of the unit were killed. The four survivors were sentenced to death by a military tribunal and executed.
