It gets really cold in those open-top military Jeeps of yesteryear.

The Canadian Army found ways to stay warm by winterizing Jeeps into some warmish rides.

Watch this classic video and see how the Canadians winterized their Jeeps.

This vintage Canadian Army news reel footage shows all the interesting ideas these intrepid soldiers could come up with. At least these soldiers were out of the wind in these customized winter Jeeps.

Necessity is the mother of invention and this video proves that is indeed the case.
