The role of the Turkish military in the formulation of policy is based on a combination of statutory obligations and the moral authority derived from its public prestige and record of past interventions. It exercises influence through a mixture of formal and informal mechanisms, both utilising official platforms, such as its participation in the NSC, and setting policy parameters through public and private expressions of opinion. The informal authority of the military as an institution far exceeds that of any politician, including the prime minister, to whom the TGS is notionally subordinate. As a result, its ability to influence policy through expressing an opinion is much greater than any reading of its statutory powers and obligations would suggest.
