An estimated one million soldiers are posted along the two-mile demilitarized zone (DMZ) that separates North and South Korea.

They've been there since the Korean War ended in 1953, making it one of the world's most heavily fortified borders, even though it's really a Cold War relic.

There are always tensions between the two countries and the BBC's Lucy Williamson got a first hand look at that when she spent a day recently with South Korean troops on the DMZ.
