The minister of defence or the chancellor is supported by the Chief of Defense (CHOD, "Generalinspekteur") and the service chiefs ("Inspekteure": Inspector of the Army, Inspector of the Air Force, Inspector of the Navy) and their respective staffs in his or her function as commander-in-chief. The CHOD and the service chiefs form the Military Command Council ("Militärischer Führungsrat") with functions similar to those of the Joint Chiefs of Staff in the United States. Subordinate to the CHOD is the Armed Forces Operational Command ("Einsatzführungskommando"). For smaller missions one of the service HQs (e.g. the Fleet Command) may exercise command and control of forces in missions abroad. The "Bundestag" must approve any foreign deployment by a simple majority. This has led to some discontent with Germany's allies about troop deployments e.g. in Afghanistan since parliamentary consent over such issues is relatively hard to achieve in Germany.
