North Korean leader Kim Jong-un has viewed artillery academy cadets carrying out a live-fire drill and stressed the importance of "constantly training the guerrilla war tactics to wipe out the enemies through rapid mobile and surprise operations," state media said Sunday. Kim oversaw the firing exercise by the 75th-term graduates of O Jin U Artillery Academy on the eve of their advance into the active commanding officers of the core arm of the Korean People's Army, according to the Korean Central News Agency (KCNA). It did not say when the exercise took place. Kim called on the academy to improve education with a focus on "constantly training the guerrilla war tactics to wipe out the enemies through rapid mobile and surprise operations in conformity with the actual conditions in the operational area," the KCNA said. The report came a day before the North holds a key parliamentary meeting Monday, where it is expected to revise its constitution by removing unification-related clauses and clarifying the nat ion's territorial boundaries, including the maritime border. The 11th session of the 14th Supreme People's Assembly (SPA) takes place nine months after North Korean leader Kim Jong-un redefined inter-Korean relations as being between "two hostile states" and vowed to no longer consider South Korea a partner for reconciliation and unification. In a previous SPA meeting in January, Kim called for constitutional changes to officially label South Korea as North Korea's "invariable principal enemy" and to codify plans for "completely occupying" the South in the event of war.
