When the implementation of political decisions has military implications, the key actors involved are: the Military Committee, composed of the Chiefs of Defence of NATO member countries; the International Military Staff, the Military Committee’s executive body; and the military command structure, composed of Allied Command Operations and Allied Command Transformation.
