Combined Air Operations Centre
Multinational headquarters for tactical and operational control of NATO Air Forces
From Wikipedia, the free encyclopedia
Combined Air Operations Centres (CAOCs) are multinational headquarters for tactical and operational control of NATO Air Forces below the Joint Force Command level. They operate within the NATO Integrated Air Defense System (NATINADS) framework.

Within the European NATO command structure, they are subordinate to NATO's Allied Air Command (AIRCOM), and superior to Control and Reporting Centres, national airspace control centres, and Regional Airspace Surveillance Coordination Centres (RASCC) such as BALTNET. NATO may also operate in Europe with static and deployable CAOCs.
Predecessor organisations of the CAOC were Air Tactical Operations Centre (ATOC) and Air Defence Operations Centre (ADOC). Until 1980 the two HQs for air attack and air defence operated autonomously.
