The Chief of the Combined Staff of Interpact is the chief of staff of the combined military forces of all full member states of Interpact during treaty-activated defensive and/or counteroffensive military operations. In the event of mutual defence treaty activation following an attack on an Interpact member, the Chief of the Combined Staff automatically assumes command of the armed forces of all member states, who are obliged to come to the aid of the member state under attack. The Chief of the Combined Staff also has jurisdiction over member states' armed forces during joint military exercises.
