If there's a military facility nearby, and it's open, they go there and they'll get care. It depends on what kind of care. If it's a traumatic injury that requires immediate surgery and critical care, then it would be 911, but all costs are covered by the defence department. So anything that's available in the community, whether in Canada, overseas, with allies, etc., anything that's required would be covered by the defence department.
