The aim is to create a fully functioning, division-sized force for rapid deployment and regular, frequent exercises. Officials involved in the planning say it will have the capacity to increase significantly in size.
The force will incorporate air and naval units as well as ground troops and will be led by British commanders, with other participating nations contributing a range of specialist troops and units. Countries involved at present include Denmark, Latvia, Estonia, Lithuania, Norway and the Netherlands. Canada has also expressed an interest in taking part.
The Financial Times also reports that Sweden and Finland may soon enter the NATO alliance.
