　　Deliberate sabotage incidents raise concerns, jammer cable cut

　　The Norwegian Defense Research Institute (FFI) installed jammers on a remote mountaintop on Andøya on the eve of the exercise to conduct electromagnetic interference tests during military exercises.

FFI Chief Researcher Anders Rødningsby said that the damaged cable was very strong and the force required to break was very great, indicating that the sabotage was likely intentional.drone jammer

　　Rødningsby pointed out that although the motives of the saboteurs were unclear, the incident brought hidden dangers to military exercises in the Nordic region.

How to protect the security of equipment has become a severe challenge facing the armies of various countries.

　　Norway's critical infrastructure has been frequently damaged, and Russia has become the main suspect

　　In recent years, critical infrastructure in many Nordic countries has been repeatedly damaged, and Russian activities have been repeatedly considered to be related to these incidents. Norwegian intelligence agencies said that since the outbreak of the Ukrainian war, tensions between Nordic countries and Russia have risen sharply. In 2022, the optical cable connecting Norway's Svalbard Islands was suspected of being sabotaged. In 2023, the Russian ship "New New Polar Bear" became the main suspect in the interruption of the Baltic gas pipeline and two communication cables.

　　As early as the beginning of 2024, Norwegian Defense Minister Bjørn Arild Gram publicly stated: "Europe is facing a full-scale invasion threat from Eastern Europe, and we are at a critical crossroads for security." Geographically, Norway is one of NATO's Nordic members and shoulders the heavy responsibility of defending the Nordic border with Russia. As Russia's potential threat to the Nordic region increases, Norway and its allies are under increasing pressure to strengthen infrastructure protection.
