In 2005, the canadian military launched Exercise Frozen Beaver…
Eleven soldiers flew in helicopters to HansIsland, a hunk of rock off the coast of Greenland that's long been claimed by both Denmark and Canada. When they landed on the half-square-mile outcropping, the troops planted a Canadian flag, ripping down the Danish colors that had been flying there since 1984.
Once they got home they mailed the confiscated flag to the Danish ambassador in Ottawa. It was the opening shot in what has become a fusillade of bizarre military posturing over the Arctic.
Among the most recent — and weirdest — incidents: Russian scientist Artur Chilingarov used a small submersible to plant a Russian flag encased in a titanium capsule on the Arctic seafloor some 13,000 feet under the North Pole.
