We've seen a whole range of improved capabilities on the part of Russia. They have been refurbishing Soviet-era bases. They have been developing a number of search and rescue stations all around the northern sea route. Some of these military capabilities obviously also have some civilian uses. They have established two Arctic brigades. They now also have an Arctic command. They have deployed a number of air defences, again in various areas around the northern sea route. It's a modernization of existing capabilities, re-establishing some capabilities that existed and also some new structures.
Yes, other Arctic nations have also been doing more in this area. For instance, Norway now has deployment closer to its border. That didn't use to be the case. The U.S., again, has marines deployed in Norway on a rotational basis. There is also more activity in terms of submarine detection. It's not just Russia. There has been a response from other Arctic states.
