I'm not sure who you mean by the engineers. We had engineers integrated with us who were military engineers.
Our modus operandi was not to do the work that we could engage Afghans to do, and that process is still continuing. You may have read of a road that's been constructed that could have been done a lot faster by hiring big pieces of machinery, but they chose to hire local Afghans to do it by hand to encourage economic development at the lowest level.
With locally engaged civilians, life, limb, and eyesight were the terms we would go by. If there was an Afghan working with us who suffered an injury in those three areas, we would certainly address it and treat him. But as for the Canadian civilians on the team, they were treated as any of our soldiers.
