There is a lot to the tactics of mission support that these nations will need to work out, it will be interesting to see how this looks a year from now.
I wonder what influence, impact if any, will this have on the Baltic nations of Estonia, Latvia, and Lithuania.
Indeed, one thing is joint training, which has been in place the past few years, but full integration is probably still a few years down the line.
I remember, for instance, that Swedish JAS39s could not fly the first few days during the Libyan action, due to issues with the NATO supplied fuel (which was used by Danish and Norwegian F16s at the same base).
The "unwritten" expectation in the region, is that Sweden will take the lead for air force integration, the Finns will take the lead for land forces, and Norway will focus on naval forces. Depending on how far the military forces of the Nordic countries will actually be integrated in the end, that seems like a logical split of responsibilities.
Also, good catch about the Baltic states. There are already some links there, of course, but I would expect these to deepen as well with the Baltic Sea becoming essentially a NATO lake now.
If someone had told me three years ago that Sweden and Finland would be NATO members, I probably would have laughed.
