The UK-led Joint Expeditionary Force (JEF), which draws on a pool of high readiness forces from nine partner nations across Europe, carried out a final validation exercise, dubbed 'Joint Warrior', between 20 April and 5 May as the force moves closer to a full operating capability later this year.
In a demonstration of readiness, air and land components of the formation, which included elements of the Danish Jutland Dragoon Regiment, Lithuanian Iron Wolf Brigade, Latvian Mechanised Infantry Brigade, and UK 3rd Battalion The Parachute Regiment, mounted a series of ‘joint validation’ tasks at the fighting in built-up area training village on Salisbury Plain in the southern UK.
The member of JEF are Britain, Latvia, Lithuania, Estonia, Norway, Netherlands, Denmark, Finland, and Sweden.
This will be useful to fight for the islands of the Baltic Sea, I imagine, should the Russians get more active than they should.
