The JEF is a coalition of ten like-minded nations (Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Netherlands, Norway, Sweden, UK), comprising high readiness forces configured to respond rapidly to crises. It can integrate into larger international operations such as those led by NATO, the UN or other security coalitions and can conduct the full spectrum of operations. It enhances the deterrence messaging of NATO and provides agile, credible and capable forces in support of JEF Participant Nation interests.
Why do we need the JEF?
In recognising the challenges to our security and national interests, it is important that we have forces able to respond appropriately. Population growth, migration, energy demands, climate change, globalisation, urbanisation, technology changes (including cyber-attacks) all contribute to challenges within the rules based international system; in addition to traditional state-on-state threats.
Furthermore, the rise of ‘fake news’ has put the importance of being first with the story at the very tip of the spear. It is of vital importance to win the battle of the narrative and the JEF has an ability to manoeuvre in this area where others cannot. These complex trends are likely to inform the future deployment of the militaries of the Participant Nations and should therefore be a focus for the force development of the JEF.
The JEF is designed to build upon these partnerships that have evolved through strong operational experience and a shared common understanding of national security threats. It provides a flexible, integrated, Joint Force that can respond quickly, anytime and in any environment. In acting together, we demonstrate the JEF’s solidarity, capability and resolve to stand together for security and stability in our region.

JEF Operating Area
As befits its membership, the core geographic areas of interest for the JEF are the High North, North Atlantic and Baltic Sea region. The military, security and political challenges we face across these areas demand active management, across institutional boundaries, and in close cooperation. The JEF is also configured to respond further afield.
