The Korean War was a Cold War conflict that took place on the Korean peninsula in Asia. The conflict ran from 1950 to 1953. The forces involved included the North Korean Army verses the U.S. Marine Corps.
While Cate Archer was infiltrating the Dumas Lumber Company location within the state of Washington she overheard two H.A.R.M. thugs talking about experiences in the Korean War. One of the thugs had been a member of the U.S. Marine Corps while in Korea. His Marine buddy had been wounded by the North Korean Army after he had started yelling at the enemy. This buddy eventually died.
