The Civilian Control Line (CCL), or the Civilian Control Zone (CCZ, ), is a line that designates an additional buffer zone to the DMZ within a distance of from the Southern Limit Line of the DMZ. Its purpose is to limit and control the entrance of civilians into the area in order to protect and maintain the security of military facilities and operations near the DMZ. The commander of the 8th US Army ordered the creation of the CCL and it was activated and first became effective in February 1954.
