The International Military Staff (IMS) is the executive body of the Military Committee, NATO’s senior military authority. It is responsible for preparing the assessments, evaluations and reports on all NATO military matters, which form the basis of discussion and decisions in the Military Committee (MC). The IMS also ensures that decisions and policies on military matters taken by the North Atlantic Council (NAC) and the MC are implemented by the appropriate NATO military bodies.
The IMS comprises some 450 military personnel supported by approximately 90 civilian personnel. It is headed by the Director General and divided into five functional divisions and several branches and support offices. It is able to move swiftly and smoothly into a 24 hours a day, seven days a week crisis mode for a limited period of time without additional personnel
The International Military Staff is the essential link between the political decision-making bodies of the Alliance and NATO’s Strategic Commanders (the Supreme Allied Commander Europe – SACEUR - and the Supreme Allied Commander, Transformation - SACT) and their staffs, liaising closely with NATO’s civilian International Staff located in the same building in Brussels.
The current DGIMS is LtGen Juergen Bornemann of the German Armed Forces.
