From a Canada Command perspective, for example, we just completed a major exercise called Exercise Vigilant Shield. That exercise focused on activities, hazards, threats across Canada that involved all the navy, army, and air force and all of the headquarters.
Operation Nanook is a joint exercise. It includes navy, army, air force, special forces personnel, civilians, military, regular and reserve. It happens every year.
We are always conducting what we call joint exercises, because we believe that if you want the real effect, you need to have the joint team there, all of the different four environments known.
