I will jump into it first.
Regardless of whether you say it's voluntary or non-voluntary, we've all joined the forces because it's essentially a calling, ma'am. It's what we do. There are times when people are very anxious to go on tour, and you could call that voluntary, but that's just because we're doing what soldiers do, ma'am. We're doing the duty we've been trained to do. That's why we joined the forces in the first place.
So in terms of voluntary and non-voluntary, there's no definite definition. I believe it should apply to all members of the military deployed in operations, whether they be international or in support of Canada within Canada. If we're doing our duty, we're doing our duty.
