 Today, we went out and utilized the DPDs, the diver propulsion devices, and it's all about maintaining currency with our diving on the Mark 25 rebreather, which is different from the scuba where you get the bubbles. This is more of a stealth device where there's no trace of the diver underwater. We're using this as a new means of transportation underwater, so you don't have to kick anymore, kind of developing new SOPs on how to take casualties in the event and compromise, and that is just what we did today. So getting the best technology for our guys is going to be pivotal in the next big fight, and so we're all extremely grateful just to have the opportunity to train here, realistically.
