There are ten JEF Participant Nations (all of which are NATO members). The Participant Nations are Estonia, Denmark, Finland, Iceland, Latvia, Lithuania, the Netherlands, Norway, Sweden and the UK as the Framework Nation.
These nations are sovereign states that come together to strengthen national and collective resilience in line with NATO Article 3, ensuring they are prepared to respond quickly and decisively to an emerging crisis. Development is enabled through political and strategic engagement, specialist working groups, collective training opportunities and interactions with Defence Attaches, Liaison Officers, and front-line personnel.
With NATO doctrine as its baseline, the JEF has strong working relationships with partners and provides a gearing between nations and NATO, where issues can be discussed regionally and quickly reacted to without the requirement for lengthy decision-making processes.
