In the next week, South Korea's defense ministry is about to launch large-scale military exercise aimed to counter threats posed by the northern neighbor.
According to a spokesman for South Korean defense ministry, the exercise will be aimed against intrusions, regional provocations and full-scale war which can be triggered by North Korea.

About 240,000 servicemen of South Korea's Army, Navy, Air Force, and Marine Corps will take part in the one-week exercise. They will be assisted by 500 American servicemen detached from the 28,000-men force deployed in South Korea.
