Go on patrol with the Canadian Rangers across the frozen Arctic

The Canadian army's recent Arctic patrol covered 3,320 miles (5,200 km) over two months in northern Manitoba, navigating through extreme conditions. This extensive mission, which saw forces travel across ice-covered terrain by snowmobile and camp in temperatures reaching -60C, is considered the largest in the history of the Canadian Rangers. The patrol followed a route that had not been attempted in 80 years.

This operation was part of Operation Nanook-Nunalivut, an annual exercise designed to reinforce Canada's military presence in the Arctic region. The BBC accompanied the Canadian Rangers during the final leg of their journey, witnessing the conclusion of this challenging and lengthy military operation.
