The Korean People's Army is made up of 1.2 million troops, making it the fourth-largest military in the world. North Korea spends more than 30 per cent of its gross domestic product on its military. About 37,000 of those troops guard the demarcation line between the two Koreas.

Seoul is a city under the gun – thousands of them, in fact. Nearly half of the South Korea's population lives in and around Seoul with an artillery range only 50 kilometres to the north. That military threat makes South Koreans nervous, says Shim Jae Hoon, a journalist for the South China Morning Post and Jane's Defence Weekly.

"They have artillery positions that can fire half a million shells a day at Seoul," he says. "Militarily we are a target, and we are a hostage of North Korea."

"It marks a historic event as it greatly encouraged and pleased the (Korean People's Army) and people that have wished to have powerful self-reliant defense capability," KCNA said. "It will contribute to defending the peace and stability on the Korean Peninsula and in the area around it."
