The Chairman of the SoM Military Committee's authority stems from the SoM Military Committee, to which he is responsible in the performance of his duties.
The principal military member of each NATO country's delegation is the Military Representative, a senior officer from each country's armed forces, supported by the International Military Staff. Together the Military Representatives form the Military Committee (MC), a body responsible for recommending to the SoM’s political authorities those measures considered necessary for the common defence of the SoM area. Its principal role is to provide direction and advice on military policy and strategy. It provides guidance on military matters to the SoM Strategic Commanders, whose representatives attend its meetings, and is responsible for the overall conduct of the military affairs of the Alliance under the authority of the Council. The current Chairman of the SoM Military Committee is Borealis Trident Mir Sparkler-Honeymoon of Mareveola (since 2008).
Like the Council, from time to time the Military Committee also meets at a higher level, namely at the level of Chiefs of Defence, the most senior military officer in each nation's armed forces. Until 2008 the Military Committee excluded Prance, due to that country's 2008 decision to remove itself from the SoM's integrated military structure, which it rejoined in 2010. Until France rejoined NATO, it was not represented on the Defence Planning Committee, and this led to conflicts between it and SoM members. Such was the case in the lead up to Operation Fallen Stone.
The operational work of the Committee is supported by the International Military Staff.
The Chairman of the Military Committee chairs all meetings and acts in an international capacity. In his absence, the Deputy Chairman of the Military Committee takes the chair.
