The Canadian Armed Forces (CAF) is Canada's unified military organization comprising the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force. The CAF is responsible for defending Canada, contributing to international peace and security through NATO and UN missions, and supporting domestic operations including emergency response. Approximately 68,000 regular force members and 27,000 reservists serve in the CAF. The military operates under civilian control through the Department of National Defence and Minister of National Defence. CAF bases and operations contribute economically to many Canadian communities. Veterans' affairs, recruitment, and military procurement are ongoing policy areas.
