Scheduled for 13 and 14 September in Ljubljana, the meeting will bring to Ljubljana around 400 attendees, among them some 150 top military personnel from NATO countries. Also in attendance will be a civil representative of Iceland, which does not have a standing army.

The meeting will go over joint missions and operations of the alliance and warfare in the modern security situation, among other things, the military said.

The Military Committee meets once a week at the level of permanent military representatives at NATO headquarters in Brussels, while the chiefs of defence meet three times a year. Two of these conferences take place in Brussels, while one each year is hosted by a member state.

The Slovenian Military has said that the conference will be a significant logistics challenge but also a great honour, especially because Slovenia will be hosting the event in the year that marks the 70th anniversary of NATO and the 15th anniversary of its big expansion and Slovenia's membership.

The conference will be chaired by Chairman of the Military Committee Air Chief Marshal Sir Stuart Peach of the UK Airforce and will be co-chaired by the Chief of the General Staff of the Slovenian Military Major General Alenka Ermenc, the only female NATO chief of defence.

The Military Committee is the second oldest permanent body in NATO after the North Atlantic Council, having been formed only months after NATO was established. It is the main advisory body in military affairs to the North Atlantic Council and the Nuclear Planning Group.
