Firearm and Canadian paramilitary question

["Peter" <spezbaby@xxxxxxxxx>]

The Canadian Forces have a paramilitary organisation called The Rangers who
act as a recce and training cadre in the north. They are civilians, but are
provided with equipment by the government. The question I have has to do
with their long arm. They are issued a WWII era Enfield.

Are their any issues caused by extreme cold on the actions of modern
firearms? Is a bolt-action enfield better suited to the climate of the
arctic, and if so why? Does anyone know anything else about the Canadian
Rangers?

Thanks
Peter
