I'll start the response to that question, and I'll ask Dave to finish off, maybe, and cover off anything I haven't.
The typical drones that we're encountering right now are the ones that have 30-minute flight times, the off-the-shelf kind. Although some have a greater payload and the technology is changing fast and distance is increasing with the fixed-wing drones, the majority are the 30-minute hobby craft. They're still a concern for us, obviously, in those kinds of protected areas where we are looking after the security of a VIP, for example. We are working extensively on countermeasures with our partners and the industry. Dave has participated in a number of research trials, also with DRDC, Defence and Research Development Canada, in order for us to look at ways to counteract any of those situations where they might pose a threat to a protected person.
With smuggling, as you mentioned, we're more than likely to see that as distances increase with fixed-wing drones. Our border with the U.S. is fairly open. I worked for many years in British Columbia, where you could just walk across the border. The need to fly a drone across wasn't terribly necessary. You could just, in the middle of the night, walk across. It's wide open. There are no fences.
We are seriously engaged in all things related to countermeasures when it comes to drones. Technology is changing fast.
I don't know if Dave wants to add anything to that.
