From Wikipedia on the Danish Navy Greenland patrols:

'Among the equipment used by the Sirius Sledge Patrol is the M1917 Enfield bolt-action rifle chambered in .30-06 Springfield, and Glock 20 pistols chambered in 10mm Auto as their previous Pistol M/49 sidearms chambered in 9mm Parabellum proved insufficient against the polar bears encountered.'
