The Tactical Mobilisation Group (TMG, ) was the special operations unit of the Turkish Army. It was founded in 1952 as part of NATO's efforts to establish a Counter-Guerrilla force in Turkey as the Turkish branch of Operation Gladio. It was disbanded in 1965, with special operations taken over by the new Special Warfare Department ().
In the 2000s it was revealed that the 1955 Istanbul pogrom was engineered by the TMG. Turkish Land Forces General Sabri Yirmibeà ÂoÃÂlu, the right-hand man of General Kemal Yamak who organised the Counter-Guerrilla through the Tactical Mobilization Group, proudly reminisced about his involvement in the riots, calling the TMG "a magnificent organization".
With the consent of the National Defense Supreme Council (), brigadier general Danià  Karabelen founded the Tactical Mobilization Group (, or STK) on 27 September 1952. Karabelen was one of sixteen soldiers (including Turgut Sunalp, Ahmet Yñldñz, Alparslan Türkeà Â, Suphi Karaman, and Fikret Ateà ÂdaÃÂlñ) who had been sent to the United States in 1948 for training in special warfare. These people were to form the core of what would later be called the Special Warfare Department (, or ÃÂHD). It has been said that the training also entailed an element of CIA recruitment.
Some full generals that later ran the department were Adnan DoÃÂu, Aydñn ðlter, Sabri Yirmibeà ÂoÃÂlu, ðbrahim Türkgenci, DoÃÂan Bayazñt, and Fevzi Türkeri. Karabelen picked Ismail Tansu as his right-hand man, and they expanded the STK in a cellular fashion. They filled the ranks, mostly with reserve officers, inducted them with an oath, and educated them before allowing them to return to civilian life. The officers were given no weapons, funding, or immediate task. The recruitment was more concentrated in the east, where an invasion was most likely to occur.
