Weapons and gear of the DMZ: South Korea's last defense

On either side of the Demilitarized Zone (DMZ), the approximately 150-mile-long, 2.4-mile-wide strip separating North Korea and South Korea, lie armies, weapons and other markers of war. 

At the observation post in Paju, a city situated just south of the world-watched 38th parallel, a South Korean solider stands. South Korea and its volatile neighbor have never officially ended the Korean War, signing an armistice that created the DMZ in 1953.
