The US Naval Institute Proceedings July 2013 edition has an article concerning US military policy in the Arctic, “When the Ice Melts,” written by three officers from the Navy, Air Force, and Army, which pays a lot of attention to the Coast Guard. Not much really new here and it appears a few months out of date, but still a good overview of the questions involved, if perhaps a bit too alarmist about the Chinese. It does advocate more Navy participation in the Arctic Shield Exercises.
Unfortunately the full article is only accessible to US Naval Institute members, but if you are a regular reader here, there is a good chance you should also be a USNI member.
