 So this unit goes and finds this remote Afghan village and they are engaged with them. They're looking in and they're assessing what do they need. And some of the leaders notice that these Afghan women every day, twice a day, they grab these huge water containers, put them on their heads, and then they walk for miles. And then they bring the water back to the village. So Eureka, the military unit says, we know what we got to do here. What do you think it is? Dig a well.
