In 1966, the Korean People's Army  deployed eight infantry divisions along the DMZ, backed by eight more infantry divisions, three motorized infantry divisions, a tank division and a collection of separate infantry and tank brigades and regiments. Its total armed forced personnel numbered 386,000. While strong, this conventional force was smaller than the South's ground forces of about 585,000, and it was unlikely that the North could deliver a knockout blow before the U.S. could deploy additional forces. The main unconventional warfare arm was the Reconnaissance Bureau of the Ministry of Defense under the operational control of the Liaison Department of the Worker's Party of Korea which included the 17th Foot Reconnaissance Brigade and the all-officer Unit 124 and 283rd Army Units. These units were all highly trained and indoctrinated, skilled in demolitions and small-unit tactics, they would usually operate in small teams of 2-12 men, lightly armed with either PPS submachine guns or AK-47s. The Reconnaissance Bureau also controlled the 23d Amphibious Brigade, which used specially made infiltration boats to operate along the South Korean coastline. The Reconnaissance Bureau could also use conventional KPA and Korean People's Navy forces to support the infiltration and exfiltration of its teams. In addition to the offensive irregular forces, North Korea also deployed several thousand operator-agitators to select, train, and supervise informants and guerrilla recruits, while others attempted to cause individual defections and unit dissatisfaction in the ROK military and generally undermine the morale of both the ROKs and the Americans.. How many more total force was the South than the North?
