At the moment, the north is very inhospitable. If we want to have a real impact in the north, we have to conduct enough exercises and collaborate enough with the other forces that train there and conduct operations there.
During the survey campaign in the Arctic that I did, the aim was, for example, to discover where gasoline caches were located, or to determine what runways could take which types of planes. All that data was foreign to us. The pilots in some aviation communities also needed to learn to fly with night vision glasses, since it is dark a lot of the time in the north. Those are the kinds of discoveries we need to make. The ground troops also have to relearn how to operate in the north.
Regarding operations with the allies, I recall that my first exercise as a helicopter pilot took place in NATO's northern flank, in Norway. We had been assigned there because at the time we were experts in operations in similar conditions. However, those competences have been lost over the years, because of the geopolitical situation and years spent in Bosnia and Afghanistan. Those are competences that must be reacquired.
