This somewhat silly movie included numerous jeeps and other war-time transport. It looks like the Sierras were substituted for Northwestern Canada. Perhaps the funniest part of the movie begins at 21:36 as a jeep rolls up behind a guy in a parka (a scene that looks fake). For some reason, two soldiers have climbed a Matterhorn-looking spire. One guy starts to fall, so the other uses a rope with a loop to keep him from falling. Then, somehow, the guy up top then climbs down on the same rope, but how does the top of the rope connect to anything?
