 All right, heel casting is a method of insertion, deploying it from a helicopter into the ocean without the use of parachutes or any other type of helicopter rope suspension equipment. We're working with the Japanese, as well as the rest of my platoon. Everything went smooth, that's just because of the precast training. We've trained as how we were going to execute the mission and by doing so kind of mitigate the language barrier. Fair enough to jump off. Usually we have about two different time warnings. They actually did quite well. They were actually maybe a little bit too eager and kind of rushed to ramp a little bit. We had to slow it down, but other than that, that was the only issue. And they performed exactly how we trained them to do. For RIMPAC, we are trying to develop interoperability with other countries in order to sort of facilitate an easier transition when we're working with foreign countries for various other real world operations.
