The US and South Korean militaries carried out a training exercise focused on "infiltrating North Korea and removing weapons of mass destruction in case of conflict," military sources told Yonhap News.
Lt. Col. Christopher B. Logan, a spokesman for the US military in South Korea, told Business Insider that the US military doesn't "discuss specific scenarios," but that "exercises are vital to the readiness of the US and our allies, and ensure we are ready and trained for combined-joint operations."
Online video of the exercise, called Warrior Strike, shows US troops training in protective gear and in urban environments, much as they might if they had to fight through a situation where nuclear, chemical, or biological weapons had been used.
The training, which took place on Dec.15, followed up a week-long air drill that involved an unprecedented number of stealth aircraft carrying out simulated bomb runs on North Korean targets.
If war broke out between the US, South Korea, and North Korea, a key task early in the conflictwould be seizing control of, or destroying, Pyongyang's weapons of mass destruction.
Though its arsenal remains secretive, experts suspect North Korea possesses chemical, biological, and nuclear weapons. North Korea has frequently threatened nuclear attacks on South Korea and the US, and demonstrated nuclear devices six times.
At the moment, China and Russia accuse the US of escalating tensions with North Korea as it increases its military drills, while the US pushes the world to implement strict sanctions on Pyongyang and refuses to accept the nation's illegally forged nuclear status.
