The founding goal of the operation was to erect a stay-behind guerrilla force to undermine a possible Soviet occupation. The goal was soon expanded to subverting communism in Turkey.

The Counter-Guerrilla initially operated out of the Turkish Armed Forces' Tactical Mobilization Group (, or STK). In 1967, the STK was renamed to the Special Warfare Department (, ÖHD). In 1994, the ÖHD became the Special Forces Command (, ÖKK).
