What is unit 684?

Unit 684 was a special forces unit within the Republic of Korea Army, also known as the ROKA. The unit was established in 1971 during the Vietnam War, with the primary objective of conducting covert operations deep behind enemy lines.

Unit 684 was comprised of highly trained soldiers who were selected based on their combat experience, physical fitness, and mental resilience. The unit underwent rigorous training in special operations tactics, unconventional warfare, and counter-insurgency tactics.

During its active years, Unit 684 carried out numerous successful missions, including reconnaissance, sabotage, and intelligence gathering operations. The unit was known for its professionalism, stealth, and effectiveness in carrying out its tasks.

In the years following the end of the Vietnam War, Unit 684 was disbanded, and its members were integrated into other special forces units within the ROKA. The unit's legacy lives on as a testament to the skill and courage of its members in carrying out some of the most challenging and dangerous missions in modern warfare.
