[Interview] Last 'Imjin Scout' brings DMZ warriors to light
From 1965 to 1991, a group of specially-trained forces conducted perilous missions inside the heavily fortified Demilitarized Zone (DMZ) dividing the two Koreas. These warriors were part of the U.S. 2nd Infantry Division. Each team consisted of 10 members and their main duty was patrolling the then-U.S. section of the DMZ. Their DMZ mission continued for three months, then another 10-member team replaced the previous one with another three-month operation inside the buffer area.
