Today it takes five or six Marines to get somebody wounded off the battlefield with something like this you could do it with one and that keeps more Marines in the fight. We are testing out the LSD to robotic meal. It's really easy to control, really easy to understand and it's a whole lot of fun. You can pretty much teach anybody in military to use it. They're walking through just simple patrol maneuvers with the machine to see where what its limits are and where where it makes most sense for it to be when the squad is on patrol. Experimentation phase is in full swing right now and we'll come back and we'll look at all the data, we'll get the feedback from all the Marines on how they feel, it can support them best and then we'll look at what it needs to look like. What right looks like at the end of the day for a a legged support system that's autonomous. We ultimately wanted to support Marines in the field. We ultimately wanted to get some of the load off their backs. The system was really good, it's a great idea and I'm glad that they're coming out that it just shows that Marine Corps changing times are changing the next 15-20 years. Stuff like this should be everywhere in the military.
