In Norway, the Norwegian Armed Forces (Forsvaret) are responsible for protecting Norway and its allies, including monitoring Norway’s airspace, digital, land, and maritime areas, maintaining the country’s borders and sovereignty, contributing to NATO and UN missions, and providing support to civil society, such as assisting the police, search and rescue, and maritime counterterrorism efforts; the military’s territorial and sovereignty defense missions are complicated by Norway’s vast sea areas, numerous islands, long and winding fjords, and difficult and mountainous terrain; a key area of emphasis is its far northern border with Russia

Norway is one of the original members of NATO, and the Alliance is a key component of Norway’s defense policy; the Forsvaret participates in NATO exercises, missions, and operations, including air policing of NATO territory, NATO’s Enhanced Forward Presence mission in the Baltic States and Eastern Europe, and standing naval missions, as well as operations in non-NATO areas, such as the Middle East

the Forsvaret also cooperates closely with the militaries of other Nordic countries through the Nordic Defense Cooperation (NORDEFCO; established 2009), which consists of Denmark, Finland, Iceland, Norway, and Sweden; Norway contributes to the UK-led Joint Expeditionary Force, a pool of high-readiness military forces from 10 Baltic and Scandinavian countries designed to respond to a wide range of contingencies in the High North, North Atlantic, and Baltic Sea regions; Norway has close military ties with the US, including rotational US military deployments and an agreement allowing for mutual defense activities and US military forces to access some Norwegian facilities

the Forsvaret's origins go back to the leidangen, defense forces which were established along the coastline in the 10th century to protect the Norwegian coast (2025)
