 Marines have to carry a certain amount of batteries when they go on a 96-hour patrol and they carry those batteries because they have to communicate. Well, if we can provide them with the capability to not have to carry so many batteries, that means they can stay out longer. They can do more patrols and they won't need to worry about being resupplied. They can sustain them on their own for a longer period of time. X-Fob is, I like to call it a shortcut. What it does is it allows us to use commercially available technologies to shorten the pathway from technology development to implementation in a Marine Corps. The leg braces that help store energy as you walk, they're small kinks that you got to work out there, like how they strap on a leg creates hotspots, but it's a phenomenal idea. And I think if the Marine Corps had that three years ago, the way that it helps assist to slow down your leg movement, it wouldn't have so much shock force on your legs. My knees would be fine. We bring a team of engineers and they actually wire up each of the systems and they're going to collect data on them throughout the week. All that data gets wrapped up into a report and then we'll make a decision to purchase in limited quantities, maybe one or two of these systems. Nothing that's here is going to be something that the Marine Corps will buy today. But the idea is to see the possibility. That's what we're looking for.
