During the early days of the war, the North Korean People’s Army never varied its tactics. It never had any need to do so. Its general maneuver was to press the ROK or American forces closely, engage with them by means of a frontal holding attack, while at the same time turning the enemy flank and infiltrating troops to the enemy rear. Against both ROK’s and United States troops, who were never able to establish a firm battle line, this tactic was ruinous.
