There were a number of other batteries that were not part of the Sicherungsstellung Nord, but which had an impact on the military defense of the region. It is not possible to define the the guns in the FLAK batteries.
The pictures represent types of German FLAK from WW1.
2 FLAK batteries (FLAK = Flug Abwehr Kanone) anti-aircraft guns belonging to the Tønder airship-base (the Zeppelin base) Accommodation for the crew A was arranged in a burial mound, with entrance from the east and west respectively. On the walls of the rooms and hallways were shelves on which the 1800 rounds to the battery was located.
The battery had one single opportunity to get into battle. They were alerted when the English airplanes bombed the Tönder airship-base (The first air strike i history from a carrier) in 1918.
