For each military mission an OHQ is chosen from a list of available facilities. The EU does not have a permanent military command structure along the lines of the North Atlantic Treaty Organization's (NATO) Allied Command Operations (ACO), although it has been agreed that ACO resources may be used for the conduct of the EU's CSDP missions. The Military Planning and Conduct Capability (MPCC), established in 2017 and to be strengthened in 2020, does however represent the EU's first step in developing a permanent OHQ.
