The Canadian Rangers stand sentinel in the farthest reaches of our country. For six decades, this dedicated group of citizen-soldiers has quietly served as Canada's eyes, ears, and voice in isolated coastal and northern communities. How does this minimally trained and lightly equipped force make a meaningful contribution to national defence and to sustainable communities? One of Canada's leading experts on northern issues answers this question using official records, extensive interviews, and on-the-ground participation in Ranger exercises from coast to coast to coast. The Canadian Rangers also tells the untold story of a successful partnership that has developed between the Canadian Forces and Aboriginal peoples, a partnership rooted in traditional knowledge and skills and characterized by acceptance and crosscultural understanding.
