Allied Forces South Norway (SONOR) was a NATO command tasked with the defense of Southern Norway. SONOR's area of responsibility included all of Norway with the adjacent sea territory excluding the three northernmost counties of Norway, which were under Allied Forces North Norway.
History Allied Forces South Norway (SONOR) and was activated in 1962 along with Allied Forces North Norway (NON) and Allied Forces Baltic Approaches. Unlike most other NATO commands SONOR was a staffed entirely by members of the Norwegian Armed Forces. Its operational headquarters was located in Stavanger and today houses NATO's Joint Warfare Centre. The commander of SONOR had three deputies: Commander Land Forces South Norway, Commander Air Forces South Norway and Commander Naval Forces South Norway. Incoming allied units would have come under the command of these three deputy commanders.
Structure 1989 In case of war SONOR had the following units at its disposal:

Naval Forces South Norway (NAVSONOR) was tasked with the defence of Southern Norway's coastal waters against Soviet naval incursions and amphibious landings. Operations to the South of Norway's coastal waters were under the command of NATO's Allied Command Channel and Allied Forces Baltic Approaches. Therefore, most major naval units of the Norwegian Navy would have come under other NATO commands, with NAVSONOR retaining control of coastal artillery units and smaller coastal defense boats. NAVSONOR also dispatched a squadron of fast attack crafts to NAVNON on a rotational basis.
