We patrol for a number of reasons, and there's not necessarily a revisit rate that drives what we're doing with respect to patrolling.
Essentially—and I know you have heard this before—our Rangers do act as our eyes and ears whether they are wearing their red hoodie or not. They are members of the communities. When you take a community-security view of the north instead of worrying about four million square kilometres of territory all the time, you worry about what's going on around those communities and within range of those Ranger patrols.
When they are out on the land hunting and fishing, if they see something odd, they report it back. That's what we expect of them. That's part of the bargain when we sign them up, and they understand and actually thrive in that role. They understand they are performing an exceptional service for their country whether they are actually on paid duty or not.
In terms of regular patrols, there are regular patrols. An annual plan is worked up and executed, but it doesn't have a weekly or monthly basis. It draws on a number of factors including the rhythms of those communities with regard to their normal hunting periods and so on. It's about having presence. It's about having regular patrols, but those are not necessarily on a weekly or monthly basis.
