 So simply put, POL stands for petroleum, oil, and lubricants that were the fuel guys. We make sure that the pilots have the fuel to fly. So that's a big picture what most people probably think of when they think of fuels, but there's other things to that too. We have a section for lab to make sure that the quality of the fuel is meeting the Air Force standards and it's safe. There's cryogenics, making sure liquid oxygen, if the planes need that so the pilots can breathe in the passengers. And then just maintaining our facilities in our trucks to make sure everything's good. And if we see a problem we catch it quick to get it taken care of. And then also accounting, making sure that we can account for all the petroleum products coming in and out. Jet fuel, diesel too. We're retraining on new aircrafts, new systems that we don't have at Mansfield at the 179th. They have some R11s and other aircrafts that we've never seen. So it's really helping us to forward our career for when we will deploy. Just knowing that you play a role, your small efforts, it all together, it makes a big difference. And so yes, we fuel aircraft and then also we help out with other missions as far as if there's diesel runs, filling forklifts, there's other career fields that we play a role in and just seeing how that's connected and how everybody's efforts together, everybody's essential to the mission. So it's awesome to think that we do play a part and everybody is important. So when I think about that, that makes me feel really great and it's rewarding.
