 We're AAVs. We're part of combat assault company third Marine Regiment. We're here aboard Marine Corps Base Hawaii doing amphibious operations. We're getting Marines pretty much comfortable doing throwing the ropes out there doing troop-to-troop transfers and getting some basic water training. When we're going out there, we got we take section of tracks at a time. One track will throw ropes to another one being the down vehicles that way if something fails in track or we got hydraulic leaks or something like that, that that track is not able to operate under its own power. That track can throw the ropes to it until it's back to either the land or ship. And then the troop-to-troop transfers, that's for if one AAV is sinking. We pretty much get them out of there. There's three stages. On that third stage is when they pretty much tracks get linked together and then they swap over to the safer track and we get them safe.
