 The overall purpose is to basically lift, in general, just infantry and anyone else from ship to shore. That is our main job. Our main mission is to bring Marines on board on a plan for assaults and raids all the way up to our 20 miles inland. We're now going to do more than 20 miles, like in Iraq, we've got a lot of stuff over there. But our actual mission is to bring Marines to the shore up to 20 miles supporting them all the way. In a desert-like environment, you've got a lot of big problems with the heat. There's a lot of heat casualties because it is a metal vehicle. And so you've got to be really careful about that. Tactically, we've got to really control our dust signatures. It's kind of hard to do. But you can see a vehicle like this a lot farther away because of its dust signature in the desert. And there's a lot of soft sand, so you have to be really careful about getting it built up in places. You can throw track really easily. On our last deployment, we actually did a lot of that with the infantry. They basically came aboard our vehicles. We asked them, hey, what do you want to learn? We taught them about our comm systems because it was different than theirs. We taught them a lot about the turret because something was to actually happen. If all the crew needed to go down and we had to have a driver up there, what if we had to have an infantry drive so a one-tracker that was left could still operate the turret? Or what if everybody went down and for some reason the infantry had to take control of the track, they could still maneuver it? So we try and teach them a lot. Every Marine or rifleman, so we try and do everything we can to learn their job and they effectiveness of their weapons so we know how close or how far we can drop them. Like for mortars, for example, knowing the range of a mortar knows that we can put them in range of the target that they got hit, so they don't have to move forward or we don't have to move back. So it's really good to know their weapons and their capabilities so we can help support them like we're supposed to. They got two, charge three. Fire. Wow. I love operating the most, driving around is fun. It's not every day you get to drive around a 26 ton vehicle or just be operating one in general. I love shooting the weapons a lot, not really the stuff that goes with it. I really enjoy using the 15-40. I love all the tactics that we have involved, the fact that we're a combat MOS and that we're literally what makes the Marine Corps the Marine Corps.
