Editing Özel Harp Dairesi (section)

==Overview==
The Özel Harp Dairesi (ÖHD, Special Warfare Department) was a clandestine special operations unit within the Turkish Armed Forces, established to conduct irregular warfare and counter-insurgency operations. Initially founded in 1952 as the Seferberlik Tetkik Kurulu (ST、区 Mobilization Group, STK), it was renamed ÖHD in 1967. The unit, also known as the Counter-Guerrilla (Kontrgerilla), was restructured in 1992 into the Special Forces Command (Özel Kuvvetler Komutanlığı, ÖKK). The ÖHD was tasked with preparing for resistance against a potential Soviet invasion but expanded its role to combat internal threats, particularly communism and separatism, often through controversial and violent means. The Counter-Guerrilla, its operational arm, was implicated in numerous acts of political violence, including assassinations, bombings, and torture, aimed at suppressing leftist and Kurdish movements during the Cold War era.
