 So the exercise we're doing today is mainly water production, so we come out here to see how much water we can produce in a 48 hour period. The gear we have out, we have the twips, which is also known as the tactical water purification system. And we have the smaller version of that, which is known as the lips, which is the light water purification system. The twips, obviously a bigger piece of machinery, purifies more water. The lips is more lightweight and it's maneuverable and you can actually load it into a high back humvee. With the twips, you're looking at about 600 gallons per hour. And with the L-whips, you're looking at about 400 gallons per hour. You're going to have your raw water pump. The raw water pump solely pulls your raw water from its source. And as it pulls that water from the lake, it stores it into that raw water bag. You have another pump that pulls that water out of that bag into a fresh water pump. And that's when the purification process starts. This is just in preparation for a water distribution point in case we get into a situation where we have to provide water to local populace or whatnot. And also to give the individual marines more experience and have them be comfortable in their gear. So definitely this train is going to make them a lot better and more confident in their gear. So if they do get put in that situation where, hey, you got to set this machine up, there's no problem to them. They know how to do it.
