It's not so much for the allies. In that particular case, there is an Arctic survival training camp that the European nations utilize, and because the local expertise happens to be within the Rangers, they have contracted them to support and provide survival training. That's not unusual. Again, it's to be able to live off the land, conducting local sustenance training and hunting and survival skills.
We also do the same thing whenever we take Rangers, for example, in support of the Arctic survival training that's done in Resolute for the air force. We bring Rangers out there to show how to do winter shelters, live off the land, how to fish in a survival context. We do that with most soldiers, and we take that training opportunity when we put them in a northern operation.
